INTRODUCTION
This manual provides information required by the operator for:
•

Normal system operations.
Procedures that can be carried out by service
representatives.

The 4341 system consists of one 3278 Display Console
Model 2A (standard) or the 3279 Color Display Console
Model 2C (optional). Optional features allow three additional
devices (3278-2A, 3279-2C Display Consoles or 3287 Model
1, 2, 1C, and 2C Printers) in any arrangement. Optional
display consoles can be assigned used as alternate operator
display consoles.

OPERATOR CONSOLE
The operator console for the 4341 consists of:
•

Operator Control Panel (OCP)

Hardware Configuration

Modes of Operation

The operator control panel has switches for basic tasks (such
as making the system operational) and lights to alert the
operator of system status.

The 4341 Processor consists of one 3278-2A (standard) or
3279-2C (optional) Display Console. Optional features allow
three additional 3278-2A. 3279-2C or 3287 devices to be
attached to the support processor and configured as needed.
The 3278-2A and 3279-2C operator console keyboard has 75
keys including 12 Program Function keys. All alphameric,
graphic. and cursor control keys are typamatic. When held
pressed, typamatic keys automatically repeat at approximately
ten operations a second.

The 3278-2A and 3279-2C Display Consoles have three
modes of operation that affect screen format: Display mode,
Printer/Keyboard mode, and Manual mode. The Display and
Printer /Keyboard modes are used under the control of the
operating system. Manual mode, which can be entered at
any time. provides control of basic system functions.

The following figure indicates the 4341 hardware
configuration.

In display mode, the 3278-2A or 3279-2C Display Console
and the optional 3287 Printer are separately addressable
devices operating as a 3270-type of operator console. Data
may be entered or displayed on the display console and
separately printed on the hard-copy printer.

Display Console/Keyboard
The Display Console is the principal device for the operator to
communicate with the system. The keyboard and the display
can control system operations as well as display the status of
the system. The display keyboard has alphameric, control,
and function keys. All keys. except the Copy key and those
keys designated for CE use only, operate when the console is
in display mode.

The 3287 Printer provides a printed copy of information that
is displayed at a display console, or of information written
from the program. Printed data appears in the same
alphameric characters and symbols that appear on a display
image. Printouts can be formatted in the same manner as a
display image. The cursor indication is not shown on the
printer output.

Manual operations (such as displaying and altering data,
loading programs, and running the systam in instruction-step
or address-compare mo'de) are performed by keying
characters from the keyboard into displays on the video
screen. The screen is used to display all actions. No
indicator lights are to be decoded. All information is
displayed on the screen, either in clear text, hexadecimal
notation, or binary zeros and ones.

When the system is in manual mode, the display console is
under control of support processor microcode. The system
uses the display console to display or alter data, control a
function, or display the results of a function. The support
processor manual functions are: to alter/display storage,
registers, PSW, UCWs, etc.• or to compare stop on addresses
or data. All manual function facilities are displayed on the
General Selection screen (Q).

SUPPORT

In printer/keyboard mode. the 3278-2A or 3279-2C Display
Console and the optional 3287 Printer share a single address.
This mode is used to emulate a 1052 for those operating
systems and programs designed for that type of operator
console. Operating messages to and from the system ara
displayed on the display console and also printed on the
coupled printer.

OPERATOR CONTROL PANEL (OCP)
The operator control panel (OCP) is on both the 3278-2A and
3279-2C keyboards. The OCP provides the facilities to
control the system power and the associated initial microcode
load and to monitor the system operating states.

This switch has a dual function. Powering on the system by
pressing this switch:
•

Test

Applies power to the processor.
IMLs the support processor. (A subsequent, nonrelated
IML of the processing unit occurs at the conclusion of the
power-on cycle).
Powers on all I/O devices that are switched to power
on/off with the processor.
IMLs the instruction processor if IML at power-on is
specified on the Program Load screen.

If system problems later occur during operational
processing, pressing Power On re-IMLs the support
processor without powering down the system. Note, that a
re-IML does not reset any PU errors.

Notes:
The 4341 requires 15 seconds of warmup time after the
main power is applied before the operator control panel
can power up the system.
The Power On/IML switch must not be pressed within
approximately 30 seconds following a power-off or a
BASIC CHECK results. The cooling fans must have time
to stop.
•

[@] ~

After initiating power-on or re-IML, do not perform any
other functions or press any key, until the power-on or
re-IML is complete. These functions cannot be aborted
as microcode is involved in a very complex sequence.
Even if you make an error, you must wait for the
sequence to be completed.

Logic Reset Key

OCP INDICATORS

This indicator turns on when a hardware malfunction exists in
the basic power (hardwire sequence), the display console, or
when the CE switch is in the CE Mode.

Note: This key is inside the machine near the diskette
drive.
This key invokes a process which attempts to restore proper
operation to the SP without reloading any code. However, to
do this, a small module is read from the diskette. Therefore,
the diskette must be operational. Ail adapters and certain
control blocks are reset; then the General Selection screen
appears.

Power Off Switch
This switch removes power from the system under contro! of
the power sequencing program resident in the support
processor.
Note: Observe the notes for Power On/IML switch above;
they apply to this switch also.

Channel-to-Channel Switch

Basic Check

Power In Process
This indicator turns on as soon as the Power On switch is
pressed. It remains on through the power-on sequence of
hardware initialization of the support processor, IML,
processor power sequence, and control unit power. At this
point it goes out, and the Power Complete light turns on.

Power Complete
This indicator turns on at the end of the power-on sequence.

If the Operator Console has a control panel. a power-off, a
Test Mode condition, an open coax cable or a console and/or
DCA hardware failure, the Basic Check indicator turns on.
When power is restored and the console is returned from
Test mode, the Basic Check indicator is reset.

System
This indicator is on when PU operations are active; for
example, during instruction processing.

Chan-Chan Disabled

Wait Indicator

This indicator is associated with the Channel-to-Channel
switch and comes on when the processor logical interface is
not connected. When lit, the operator can power down the
system and not lose data or hang up the other processor.

This indicator is on when the processor is idle (processing
clock is running, but no instruction processing is taking place).

The channel-to-channel switch is required for systems having
a channel-to-channel adapter feature. This switch is
activated to make a logical interface connection of one
processor to another processor for data sharing purposes.
Normally, it is activated only two times during the workday:
1. After power-up completion. Activation places the
interface in the enabled mode and causes the Disable
indicator to go out.
2. Prior to powering off. Power Off should not be pressed
until the Chan-Chan Disabled indicator comes on.

Lamp Test Switch
This switch is used by the operator to check whether or not
aI/ indicators are working.

3278 DISPLAY CONSOLE MODEL 2A

CONSOLE CHARACTERISTICS

3278 MODEL 2A OPERATOR CONTROLS

The 3278 Display Console Model 2A has a screen size of
1920 characters, 24 lines at 80 characters per line. The
bottom four (21-24) lines are reserved for system status
information. Both uppercase and lowercase characters can
be displayed.

Brightness Control

Audible Alarm Volume Control

You can adjust the brightness of the characters displayed on
the screen by turning the brightness control knob to the left
or to the right. Turning it to the right makes the display
image brighter; to the left, dimmer. Find the setting most
convenient and comfortable for your viewing. If held all the
way to the right, a raster pattern is displayed for test
purposes. This raster pattern can vary between consoles.

If the display console has the Audible Alarm feature, the
volume control for the audible alarm is at the outside of the
screen contrast control. Turning this control clockwise
increases the sound level; turning the control
counterclockwise decreases the sound level. To test or adjust
the audible alarm, refer to "Audible Alarm Feature."

Display Image
Normal/Test Switch

The display image format is divided into three functional
areas.

When you are operating the display station, have this switch
in the Normal position.
Use the Test position of this switch when you have a
problem with the display console and you perform the
Problem Determination Procedures. When you place the
switch in. the Test position, the operator can perform tests
that help diagnose the cause of the problem.

DISPLAY /KEYBOARD

KEYBOARD CHARACTERISTICS

Key Symbols

Symbols and Punctuation Marks

The 3278-2A and 3279-2C keyboards enable the operator to
communicate with the system. Most functions are available
in the stopped and running states of the system.

Instead of language, the following symbols appear on the
display keyboard:

These characters are in two groups because of their physical
locations. The first group contains the symbols that are on
the upper part of the key top that have numerals 1 through 0
on the lower half. The second group is on keys that have
two special symbols on them. The display symbols that
appear on the upper half of a key require pressing of the shift
key. All the symbol and punctuation mark keys are typamatic
when held down.

The characters that can be displayed consist of 26
uppercase and 26 lowercase alphabetic characters, 10
numeric characters, and 32 symbols and punctuation marks.
The keyboard also contains input control keys, cursor control
keys, program function keys, and system function keys.
Keys that have two characters on the key tops can display
either of them depending upon the position of the shift key.
The lower character displays when the keyboard is in the
unshifted mode (the shift key not pressed). To display the
upper character, hold the shift key down or press the shift
lock key before pressing the character key.
Those keys that appear on the front face of indicated keys
on the keyboard are program function keys and system
function keys. To select one of these functions, hold the ALT
key down while pressing the key that indicates the specific
function you want.

A majority of the keys have the typamatic feature. For
example, if you hold the key down, the character or function
automatically repeats at a rate of approximately ten
operations per second until you release the key. The keys
that have this capability are:
Character keys (alphabetic, numeric, and special
characters).

Shift and Shift Lock
The SHIFT and SHIFT LOCK keys are the same as on a
standard typewriter keyboard. When either the left or the
right SHIFT key is pressed, the upper symbols shown on the
key tops are displayed when their respective keys are
pressed. If the character key has no upper symbol (such as
the alphabetic keys), the uppercase characters appear on the
screen. The SHIFT keys are nonlocking and must be held
down.
Pressing the SHIFT LOCK key locks the keyboard in the
shifted (uppercase) mode. When the SHIFT LOCK key is
used, you need not hold thl;! SHIFT key down. This frees
both hands for typing. Pressing either SHIFT key resets the
SHIFT LOCK to return the keyboard to the unshifted
(lowercase) mode.

ALT
The ALT key selects the function that appears on the face of
specific keys. To invoke the alternate function, hold the ALT
key down and then press the desired function key.

Moving Cursor to Beginning of Field

Moving Cursor One Character Space

New Line Key

Horizontal Positioning

The New Line key moves the cursor to the first unprotected
character location of the next line. If all character positions of
the next line or lines are protected, the cursor continues as
many lines as necessary to the first unprotected field. If all
character positions on the display screen are protected, the
cursor is repositioned to the first character location on the
first line. The New Line key is typamatic and moves the
cursor quickly from line to line.

Pressing either of the two horizontal keys (right or left) moves
the cursor in the direction of the arrow, one character position
at a time, including unprotected and protected alphameric
character and attribute character locations. These keys can
cause the cursor to wrap and reposition the cursor to the next
or preceding line of characters. These keys are typamatic. If
the cursor is positioned in a protected field or attribute
position, no data can be entered at that location.

Tab Key

Vertical Positioning Keys

Pressing the Tab key moves the cursor to the right to the first
character location of the next unprotected data field.

Operating either of two vertical cursor positioning keys (cursor
up, cursor down) moves the cursor in the direction of the
arrow, one line at a time. These keys can cause the cursor to
wrap vertically. The cursor stays in the same character
column. These keys are typamatic.

Pressing the Tab key moves the cursor to the first character
location on line 1 if the screen is not formatted or if there are
no unprotected data fields. Tab key is typamatic and moves
the cursor quickly from field to field.

Backspace Key

Space Bar
A space is considered an actual character that occupies a
position on the screen. When the space bar is pressed, a
space is entered on the screen and replaces whatever
character is presently in that position. For this reason, the
space bar should not be used to position the cursor. The
space bar is typamatic.

Back Tab Key
The Back Tab key moves the cursor back to the first
character position in an input field.

Pressing the Backspace key moves the cursor one character
space to the left for each pressing of the key. This key
operates exactly like the horizontal (left) positioning key and is
also typamatic.

If the cursor is already in the first character position of an
input field, pressing the Back Tab key moves the cursor back
to the first character position of the preceding input field.
Pressing the Back Tab key moves the cursor to the first
character position on line 1 if the screen is not formatted or if
there are no unprotected data fields.

Cursor Control Keys
The cursor keys control the vertical and horizontal movement
of the cursor. These keys position the cursor without
affecting the information on the screen.
The two types of cursor control keys are:
1. Those that move the cursor to the first character location
in an unprotected field.

Home Key
Pressing the Home key repositions the cursor to the first
unprotected character position on the screen. If there are no
unprotected character positions on the screen, the cursor is
placed at the first character position on line 1.

2. Those that move the cursor one character position at a
time.

Reset

Cnel (Display Mode)

Pressing the RESET key restores the keyboard to its normal
mode of operation. The keyboard is inhibited whenever an
attempt is made to enter a character into a protected location.
This can occur when the cursor is moved (via the cursor keys)
to a protected field. When the keyboard is inhibited. the
alphameric and symbol keys can be pressed. but no action
results. The message INHIBITED appears on line 25 on the
display. To remove the inhibit, press the RESET key.

Pressing the CNCL (cancel) key generates an attention
interrupt to the operating system in display mode.

To find the next unprotected field (and avoid inhibiting the
keyboard again). press the Tab or Back Tab key.

All the keyboard control keys perform normally when in
insert mode.

Cncl (Printer/Keyboard Mode)
During a read operation, the CNCL key initiates a cancel
response to the channel. The cancel response is a channel
end with exception. The input area is cleared and protected
and an asterisk (*) is written in the display area. No data is
transferred across the channel. If no Read is in progress, the
ALARM indicator is cleared and the keyboard is unlocked.

Pressing the Delete key when the cursor is located in an
unprotected field deletes the character at the cursor position.
All characters in the field to the right of that position and on
the same line are then shifted left one position and a null
character is added to the end.
The Delete key is active for the display, printer/keyboard, or
manual mode.

Erase Input
Pressing the ERASE INPUT key erases all input fields on the
screen. On a permanently displayed document with blanks to
fill in, only those areas in which you can enter data are
erased. The cursor moves to the first character position in
the first field in which you can begin keying input data.
Pressing the ERASE INPUT key for a screen with no input
fields erases nothing. The cursor moves to the first character
position on line 1.
Pressing the ERASE INPUT key for an unformatted screen
erases all character positions. The cursor moves to the first
character position on line 1.

enel (Manual Mode)

In display mode, the ENTER key causes an attention status
and sets an attention identifier (AID). The software performs
a subsequent Read command to obtain the AID and any
entered data.

The message FUNCTION KEY IGNORED is displayed if the
CNCL key is pressed while in manual mode.

Note: Before the ENTER key is pressed. the keyed in data is
displayed on the screen and can be changed or corrected.

Req (Display Mode)
Pressing the REQ key generates an attention interrupt to the
operating system in display mode.

Enter (Printer/Keyboard Mode)
During a read operation, pressing the ENTER key signals that
data entry is complete and transfers the input data to the
channel. The data is read, and the input area is cleared and
protected. If no Read is in progress, the ALARM indicator is
cleared and the keyboard unlocked.
Note: Before the ENTER key is pressed. the keyed in data is
displayed on the screen and can be changed or corrected.

FEATURES

SECURITY KEYLOCK (Optional Feature)

AUDIBLE ALARM FEATURE

The Security Keylock feature is an optional feature and may
not be installed on all systems. On the 4341, it has the
following characteristics:

A high-pitched tone sounds for about one second when the
audible alarm is activated on the display console.

•

A hardware feature on the display console.
Security keylock microcode is installed on all systems, but
is only activated when the Security Keylock feature is
installed.

•

All functions are normal when:
-

Security Keylock feature is not installed
Security Keylock feature is ON.

When Security Keylock is OFF:
-

-

Keyboard is locked
Console is blank
INHIBITED indicator on line 25 is on
Intervention required is the response to application
programs
No power-on/IML can be done.

Note: If the main display console is off and the
Power-On/IML key is pressed, a message appears on the
screen of all unlocked and operational display consoles on
the system. This indicates that the CHG DPLY key should
be pressed on the console from which the power-on/IML is
to continue. The key is ignored if it is pressed on a console
with the security lock in the OFF position, However, if the
lock is turned to the ON position and the CHG DPLY key is
pressed, the power-on/IML continues from that console.

The audible alarm always sounds when you enter a
character into the next to last character pOSition on your
screen. The cursor wraps from the last character position on
the screen after a character is keyed into that last position.
This is normal operation. The alarm warns that to key
another character after the cursor has wrapped, enters it into
the first character position on line 1 of your screen and
destroys the data already displayed there.
The computer program can also activate the alarm. To do
so, the program sends a signal to your display. The User's
Guide for that program indicates if the audible alarm will
sound and, if so, the different reasons for sounding it.
The volume of the audible alarm is adjustable. The
adjustment control is located at the outside of the screen.
Generally, it has been set for a normal operating environment.
To test the volume level. the next-to-Iast character position
must be in an unprotected input field. If your display station
does not have have an unprotected input field in this area of
the screen, check the application program User's Guide or
ask your supervisor for instructions to obtain one. When you
have an unprotected input field in this area of this area of the
screen, move the cursor and key in a character in the
next-to-Iast position on the screen. Then, listen to the level
of the alarm. To check the sound level again, press the
backspace key and then a character key. If the sound is not
at the desired volume, adjust the alarm control and test the
sound level again. When the volume is adjusted for your
environment, press the ERASE INPUT key.

3287 PRINTER

PRINTER CHARACTERISTICS
The 3287 Printer Model 1 or 2 is a compact, desk-top, matrix
printer with a nominal print rate of 80 characters per second
(cps) for Model 1 and 120 characters per second for Model 2.
The 3287 Printer Models 1C and 2C print in four colors:
red, blue, green, and black. The basic printer prints fields in
one of four colors as determined by the existing field
protection and intensity attributes.
The 3287 Model 1C rate is 80 cps and the 2C is 120 cps at
maximum print rate for each color on a line. Print positions
1-120 can be printed in any of the four colors. Print positions
121-132 can only be printed in black.
A maximum of three hard-copy printers (3287s) can be on
each system, but none is standard. If a hard-copy printer is
installed, it must be configured on the System Configuration
screen (QFS). When a 3287 is optionally coupled as a
hard-copy device in printer/keyboard mode, it prints ail data
transferred across the channel interface. The data is arranged
in lines of 126 or less characters as they would appear on a
printer/keyboard printer. Each line is printed as soon as it is
completed. A line is complete when one of the following
conditions occurs:
126 bytes of data are received.
•

A new-line character (X'15') is found in a Write or
Write-ACR command data stream.

•

All data is received on a Write-ACR command.

o

After a Read command is executed.

•

A system or selective reset occurs.

Note that. after a Write command (X'01') is executed, if a
complete line has not been accumulated, the last partial line
is not printed. The data is accumulated in the 3287 buffer
and is printed when the line is compJeted by succeeding
commands. The printer appears busy to a COpy key request .
at this time.
A system or selective reset causes a line feed if no data is
present in the buffer.
The 3287 Printer provides an automatic printout when
attached to the system in printer/keyboard mode, or it can be
separately addressed by the system and it responds with the
equivalent 3270 status and sense information, when the
hard-copy printer is in display mode.

Copy Mode
The 3287 can be used to obtain local copies from the
Display Console that is in manual mode, when the following
conditions are met:
•

A copy key device has been configured. The 3287 to be
used for local copy must be specified on the Program
load screen (Ql) or by using the K-selection. This makes
the 3287 available for shared use with the operating
system.

•

The 3287 is not busy. The 3287 can be busy because of
the following conditions:
In display mode, the 3287 is executing a 3270 CCW
command, or the last write command does not specify
Start Print in the WCC. In this condition, the printer is
considered to have accepted data in preparation for a
later print operation.
In printer/keyboard mode, an incomplete line is being
saved in the 3287 buffer for later printing.
-

•

A previous COpy key request is not complete.

The 3287 is operational.

The copy operation overwrites the 3287 buffer with the
console display buffer. After printing is completed, the 3287
buffer is cleared. The printer output is formatted in 80 lines
with NL, EM, and CR characters printed as spaces. Null lines
are suppressed.
If a CCW command is received while a local copy is in
progress, the command is queued until copy is complete.
The command is then executed normally.

Audible Alann
An audible alarm sounds a continuous, one-second beep
when the 3287 printer enters the end-of-form condition or
when a host-initiated request is received. The audible alarm
is also operational in offline mode. The audible alarm knob,
located under the left platen access cover, controls the alarm
voillme.
To reset the alarm, press HOLD PRINT, and then press
ENABLE PRINT.

MODES OF OPERATION

PRINTER/KEYBOARD MODE

80

column:
line:

lr-----L----------//'--------------------------------------------~

The printer ikeyboard emulation mode allows the system to
run operating systems and programs designed for that type of
operator console.

DIS P LAY ARE A

In printer/keyboard mode, the display console shares the
same address with a 3287 Printer. The 3287 Printer prints all
data read from or written to the main console display. The
main console displays 18 lines instead of the normal 20 lines.
A maximum of 126 characters can be entered at one time
from the console display keyboard. Line 19 and columns
1-46 of line lOare reserved for data input. Columns 48- 79
of line 20 are for indicators when in printer/keyboard mode.
During printer /keyboard mode, hard-copy cannot be
obtained, if a printer is not coupled or the system does not
heve a printer attached. The addresStes are assigned and the
coupling assigned from the Program Load screen. For more
detail about assignments, see "Program load Screen." The
main display console and printer responds to
printer /keyboard commands and send status and sense
information back to the system. The following sections
provide detailed information on using the display console and
3287 Printer in printer/keyboard mode.
The printer/keyboard mode is called emulation mode in
some of the 4341 documents. In this manual,
printer / keyboard operations are referred to as
printer/kfIYboard mode or Ptr/Kybd mode. The Display
Consoles and 3287 Printers are attached to the 4341
Processor via the support processor and are addressed via
I/O instructions to channel 0 addresses. The device
addresses used on channel 0 and the coupling assignment are
selected by the operator and can be modified at any time. A
maximum of two printer/keyboard devices can be configured
at one time. The standard configuration of the 4341 system
has one 3278- 2A Display Console or 3279-2C which is the
optional Display Console. Optional features allow three
additional 3278-2A/3279-2C/3287 devices to be attached.
These are configured from the Program Load screen. The
3278-2A and 3279-2C keyboard has 75 keys including 12
program function keys. All alphameric, graphic, and cursor
control keys are typamatic.

Input Area
The input area is defined by an attribute at line 18 column 80
and contains 126 characters on lines 19 and 20. This area is
unprotected only when a Read command is in progress
(PROCEED displayed). At other times, it is protected from
operator alteration. The operator may enter and modify data
for the Read, up to 126 characters, in this ares. When the
ENTER or CNCl key is pressed, the data in the input area is
transferred across the channel. Data accepted by the channel
for a Read command is moved to the display area and
printed. If the channel stopped data transfer before all data
entered by the operator is sent, only that data accepted
appears in the display area.
The field initially contains all nulls. These are compressed
out of the Read data and not transferred to the channel. The
SPACE BAR must be used to enter spaces. Cursor
movement keys leave nulls in the input area which are
compressed from the data.

~------------/I'----------------------------------------------~
OPERATOR INFORMATION AREA
~--------------//----------------------------------------~

Display Console

Display Area

In printer/keyboard mode, the entire 20-lin8 system mode
screen is controlled by the emulation module. After the
screen is in printer/k::yboard mode and made ready, the
operator is only able to enter data on the screen when a Read
command is issued. At other times. the entire display is
protected from operator alteration.

The display area starts in line 1 column 1 and ends on line 18
column 79. lines 1 -18 display the last 18 lines written or
read to the device i3278-2A/3279·-2CI. Lines 19 and 20 are
a 126-cilarscter input area with line 20 columns 48-79 used
for emulate indicators. The data is organized into lines
corresponding to lines of printer/keyboard printer output.
Each new line begins in column 1 of a display area line. A
line !onger than 80 characters (the display area line length),
wraps to the next line in the display area, to a maximum of
126 characters (the printer line length). When the 18-line
display area is filled. the next new line causes the display
area to be scrolled by 6 lines. lines 7-18 move to the top of
of the screen, and lines 13-18 are cleared and ready for
additional input.

In order to allow the maximum amount of data to be
displayed at all times in the display area, multiple New line
characters (NL=X'15') in a write data stream result in only one
blank line on the display. Multiple blank lines caused by Nl
characters are displayed as only one blank line. This prevents
data from being scrolled off the screen in cases where New
line characters are added to space the printer output.
Note: Line 25 of the display console is used exclusively for
indication of console and keyboard status.

Indicator Area
The indicator area is a brightened field on line 20 columns
48-79 and is 32 characters in length. Columns 47 and 80 are
attribute characters. This area is used to contain visual
indicators signaling the state of the printer/keyboard device
•being emulated.
.
The indicators displayed on line 20 are PROCEED.
REQUEST. ALARM. and INlV-REQO. They are used in
printer/keyboard mode. This brightened field highlights the
indicators above that of data.

Proceed
This indicator appears whenever there is a Read command in
progress. Only at this time may the operator enter data in
the input area. PROCEED is cleared when the READ
command is ended. by one of the following conditions:
•

Normal ending caused by ENTER or CNCL key.

o

A system or selective reset.

•

A Halt Device or Halt I/O instruction issued to the device.

A brief description of each command is summarized in the
following section. In the descriptions. a 3287 Printer is
assumed to be coupled as a hard-copy device. If no printer
is coupled. ending status for a command is presented to the
channel after the data has been placed in the
3278-2A/3279-2C display area.

Command Definitions (Printer/Keyboard Mode)
. Request
This indicates that a REQ (Request) key attention status has
been stacked because the device is busy executing a
command. When the current operation is completed. the
attention status is presented to the channel and the
REQUEST indicator is cleared. A system or selective reset
also clears the REQUEST indicator.

Alarm
This indicator appears and the audible alarm sounds
whenever an Alarm command is reCeived. The indicator is
cleared by one of the following:
•

Pressing a Program Function (PF) key at any time.

•

Pressing the ENTER .or CNCL key when PROCEED is not
displayed.

•

System or selective reset condition.

The Intervention-Required indicator appears if the 3287
Printer coupled as a hard-copy device becomes not ready.
This condition can occur when end-of-form. power off. or
other check conditions are present. At this time. a Start I/O
is not accepted. When the check condition is cleared. the
indicator is cleared. and device-end status is presented to the
channel.

This control command causes the audible alarm on the
display console to be sounded and the ALARM indicator to
be displayed. if the display is NOT READY, the command
functions as a NOP. Immediate channel end and device end
are presented as initial status for this command. The
command is accepted even if an intervention-required
condition exists.

NOP
This control command results in an immediate channel end
and device end. No action is performed in the device.' This
command may be used to cause a command chain to end
with a combined channel end and device end.

When the Read-Inquiry command is received. the input area
is unprotected and the PROCEED indicator is displayed. The
command then waits until the operator signals that data entry
is completed by pressing the ENTER or CNCL key. If the
ENTER key is pressed. the data is read from the input area
and transferred to the channel. A channel end is presented
after data transfer; then any data the channel accepted is
written to the display area and printed on the printer. If the
CNCL key is pressed. a channel end with unit exception
status is presented to the channel. and an asterisk (*1 is
written to the display area and printed. After printing is
completed. in either of the above cases. device end is sent to
terminate the command.

Timing (Printer/Keyboard Mode)
In printer/keyboard mode. the time taken to execute a
command differs from all other printer/keyboard devices.
Typically. the time from SIO to channel end is much shorter.
and the time from channel end to device end is longer. This
is because buffering takes place. and printing is not started
until a complete line is received. When running in uncoupled
mode (3278-2A or 3279-2C without 3287 Printer). a timing
delay of 0.5 seconds per line is added to keep the displiiyarea from changing faster than it can be read.

Keyboard Deviations (Printer/Keyboard Mode)

Sense I/O
The Sense I/O command facilitates device type identification.
If the device. is not busy the data transferred (in
printer / keyboard mode) is a constant seven bytes:
X' FF4341 001 05200'. This command is executed even when
the device is not ready.

Alarm

Read-Inquiry
Intv-Reqd

One byte of sense information is transferred in response to a
Sense command. After the sense byte is accepted.
channel-end and device-end status are presented as ending
status. The sense byte is reset at the initiation of any
command except a NOP. The sense byte is reset after the
Sense command is executed. The sense byte is defined
below:

Restrictions and Deviations (Printer/Keyboard
Mode)
.

Write

The 3278-2A and 3279-2C keyboard differs in both the
number of keys and the keyboard layout. All of the keys on
the 3278-2A and 3279-2C can be used even if the printer
has no corresponding key. It is. therefore, possible to read
and write characters which are not implemented on a
printer /keyboard device. The CARRIAGE RETURN key on a
printer /keyboard is not implemented either physically on the
3278-2A/3279-2C or logically in the printer/keyboard
emulation module. Programs which require the use of the
RETURN key do not operate in 4341 printer/keyboard mode.

Upon receipt of the Write command. the data is transferred
from the channel to an internal buffer and then processed, a
line at a time. to the display area on the display console and
printed on the 3287 Printer. When all of the data has been
received. channel-end status is returned. and the last line is
processed. If the last line is not complete (ended with
new-line character or 126 bytes). device-end status is sent
after the data has been placed in the display area and saved
in the printer buffer without printing. If the command ends
with a complete line. device-end status is sent when printing
is finished.
The Write command continues requesting data from the
channel until the channel' stops data transfer. This occurs
when the CCW count reaches zero. Therefore. incorrect
length channel status is always indicated with a zero residual
count unless the Suppress Incorrect Length Indicator (SILl)
flag is on in the CCW.

Write-ACR (Automatic Carriage Return)
This command is executed identically to the Write command
except at the end of data processing. The printer performs
the automatic carriage return. and perform the automatic
carriage return.

The display mode of operation enables the 4341 to run
operating systems and programs designed for cathode-ray
tube (CRT) type console with IBM 3270 support. For detailed
information on IBM 3270 support, refer to IBM 3270
Information Display System Component Description,
GA27-2749.

DIS P lAY ARE A

The console devices appear to the software as local channel
attached devices that support the 3272 command set. Each
console device appears as a separate address to the
operating system. A maximum of four console devices is
supported: the standard 3278-2A or the optional 3279-2C
and up to three optional 3278-2A/3279-2C/3287 devices in
any combination.
The display console provides a 20-line (1600-byte) user
accessible buffer. The last four lines on the display are
reserved for displaying 4341 Processor status and- are not
available to the user for either reading or writing. The 3287
Printers has a 24-line (1920-byte) user accessible buffer.
The device addresses to be used in display mode are
selectable by the operator by using the Console Functions
Program Load screen (QlI.

Display Console
When the display console is in display mode, the entire
20-line user buffer is controlled by software. The usar buffer
may be accessed by 3270 Read, Write. and Control
commands. lines 21 through 24 are reserved to display 4341
Processor status. Any attempt to access lines 21 through 24
by the user is rejected as invalid buffer addresses and causes
an operation check sense byte to be set. A 25th line,
separated from the other lines by a solid line, displays
console status indicators. line 25 is also unavailable to the
user. The 3278-2A and 3279-2C keyboard is for
communicating with system. In display mode, the display
contains an operating system or user-defined screen that may
be either formatted or unformatted. Formatted screens
contain fields that can be protected or unprotected from
keyboard alteration, brightened for highlighting purposes, or
nondisplayable for security reasons.

Read Buffer
This command causes all data in the device buffer to be
transferred to main storage. The data stream consists of a
read heading followed by the device buffer data. The read
heading is three bytes: a 1-byte AID character followed by a
2-byte cursor address. The buffer data has a Start Field (SF)

A brief description of each command is summarized in the
following section. In the descriptions, the 3278-2A/3279-2C
or 3287 is assumed to be ready and no programming or
device errors occur. References to a device refer to either a
3278-2A or 3279-2C Display Console or a 3287 Printer.

This command causes all unprotected fields in the device
buffer to be cleared to nulls. The Modified Data Tags (MDT)
are reset to zero for each unprotected field, and the cursor is
positioned to the first unprotected character location on the
screen. Channel-end status is presented as initial status to
the SIO, and device-end status is sent when the erase is
completed.

Erase/Write
This command performs two functions: a buffer erase
operation, then a write operation. The erase operation clears
the device buffer to nulls and sets the cursor and current
buffer address to location O. The write operation is
performed exactly as the Write command.

NOP
This control command results in an immediate channel end
and device end. No action is performed in the device. This
command can be used to cause a command chain to end
with a combined channel end and device end or to modify the
initial buffer address position for a subsequent command in a
chain.

The Read Modified command performs one of two functions
based on the value of the current AID character. A Short
Read is performed if the AID character is from a REQ (PA1)
or CNCL (PA2) key. The Short Read only transfers the AID
byte to identify which key was pressed (no data is included).
The read modified data function is performed for all other
AID characters. The data stream consists of a read heading
and the data from modified fields. The read heading consists
of the AID character and the two-byte cursor address. The
data for each modified field is preceded by a Set Buffer
Address order code with a two-byte buffer address of the
first character position in the field (the attribute address + 1).
An unformatted screen results in a read modified data stream
consisting. of the read heading and all data in the buffer
because modification of data cannot be determined. All null
characters are suppressed from the data transferred.

Select
This control command is implemented for 3270 compatibility,
and no function is performed internally. Channel-end status
is presented as initial status to the SIO, and device-end
status is generated immediately after.

Sense
One byte of sense information is transferred in response to a
Sense command. After the sense byte is accepted,
channel-end and device-end status are presented as ending
status. The sense byte is reset at the initiation of any
command except a NOP. The sense byte is reset after the
Sense command is executed. The sense byte is defined

Sense I/O

Restrictions and Deviations (Display Mode)

The Sense I/O command facilitates device-type identification.
If the device is not busy, the data transferred (in display
mode) is a constant seven bytes: X'FF43410032782A' for
3278-2A Display Console. 3279-2C FF43410032792C and
X'FF434100328700' for a 3287 or 3268 Printer. This command is
executed even when the device is not ready.

Timing
The time taken to execute a command may differ from other
3270 control units/devices. Programs depending on the time
to execute a command cannot be assumed to operate
correctly in display mode.

Write
Upon receipt of the Write command, the data is transferred
from the channel to an internal buffer and then processed to
the device. When all of the data has been received,
channel-end status is returned, and the last buffer is
processed. Device-end status is sent after the last buffer has
been processed.
The Write command continues requesting data from the
channel until the channel stops data transfer when the CCW
count reaches zero. Therefore, incorrect length channel status
is always indicated by a zero residual count unless the
Suppress Incorrect Length indicator (Sill) flag is on in the
CCW.

MANUAL MODE

3278-2A and 3279-2C Buffer
The 3278-2A and 3279-2C buffer is not completely available
for use by the Operating System or user program. Lines 21
through 24 are reserved for 4341 Processor use and are
unavailable for programmed use. Therefore, programs written
for a 24 line 3270 terminal do not execute correctly without
some alterations. Generally, an attempt to use such a
program results in an error when access lines 21 through 24
is attempted. The error causes unit-check status to be
presented and operation-check sense to be set.

Keyboard Deviations
The 3278-2A and 3279-2C keyboard differs from a standard·
3277 or 3278 keyboard layout. Several keys are either not in
the standard position or not implemented. Programs requiring
the keys that have not been implemented may not be able to
use the 3278-2A and 3279-2C for a input device. For the
following keys a difference exists between the 3278-2A
/3279-2C and other 3270 display units.

In manual mode, the following functions are provided:

Operation Check Error Handling
Write command data is internally buffered before it is
processed and written to the device. Therefore, an operation
check as the result of an invalid buffer address is not
detected when the invalid data byte is received from the
channel but at some later time. It is likely that more data has
been received from the channel and possibly that channel end
may have been sent before the operation check occurred.
The residual count field is unpredictable in this case and
cannot be used to determine precisely the location of the
error in the write data stream.

Display Console
In manual mode, the screen configuration depends upon the
function that is being used. For detailed information, refer to
Manual Functions.

Console/Printer Sensing Conditions

Hold-Print Timeout (3287 Only)

The following sensing conditions can occur while operating
the system.

When the hold-print condition has lasted more than ten
minutes. an intervention-required condition exists and is
reported to a Sense command.

Not Ready
When the device is not ready. all commands except Sense
are rejected.

Power Off
When the device is not powered on. an intervention-required
condition exists and is reported to a Sense command.

Test Mode
When the device is in test mode (TEST/NORMAL switch in
TEST position). an intervention-required condition exists and
is reported to a Sense command.

Device Not Functional
If the device hardware is failing. or the device is not
connected or configured correctly. an intervention-required or
equipment-check condition exists and is reported to a Sense
command.

End-of-Forms (3287 Only)

(

(

Operation Check (Display Mode)
An operation-check occurs when invalid data is received in
the data for a Write or Erase/Write command. This error is a
programming error which cannot be recovered from by
software retry. A programmer must inspect the data to locate
the invalid condition. The following conditions may cause an
operation check:
Invalid buffer address specified in a SBA. RA. or EUA
order. A buffer address is invalid when it references a
location past the end of the user buffer area (20 lines on a
3278-2A/3279-2C or 24 lines on a 3287).
Incomplete order sequence for SBA. RA. EUA. or SF
order. An order requiring multiple data bytes was not
complete at the end of the data stream.
The start print bit was set in the WCC for a Write or
Erase/Write command and chaining is indicated. Printing
is suppressed and command chaining is canceled.
An operation check sets unit-check and device-end status
to be sent. combined with channel end. if it has not already
been sent. The residual count in the channel status word is
unpredictable and cannot be used to determine the location of
the invalid order. The device buffer is modified with all data
processed before the invalid order.

When the end-of-forms· switch indicates no paper is in the
printer. and a one-minute timeout condition occurs. an
intervention-required condition exists and is reported to a
Sense command. This delay is incorporated in the 3287 to
allow the operator to correct the end-of-forms condition and
have the 3287 automatically continue printing with no errors
reported or software retry required. The end-of-forms
condition causes the audible alarm to sound until the HOLD
PRINT switch is pressed. The end-of-forms should be
cleared by pressing the HOLD PRINT switch. replacing the
forms. then pressing the ENABLE PRINT switch to allow
printing to continue.

ADDITIONAL FEATURES

SECURITY KEYlOCK (Optional Feature)

AUDIBLE ALARM FEATURE

The Security Keylock Feature is an optional feature and may
not be installed on all systems. On the 4341, it has the
following characteristics:

The 3278 display can be equipped with an audible alarm.
This is a feature of your display that can't be seen but that
you should be aware of.

•

A hardware feature on the 3278 Display Console 2A.

•

Security Keylock microcode is installed on all systems; but
it is only activated when the Security Keylock Feature is
installed.

A high-pitched tone sounds for about one second everytime
the audible alarm is activated.

•

All functions are normal when:
- Security Keylock Feature is not installed
- Security Keylock Feature is ON.

•

When Security Keylock is OFF:
Keyboard is locked
Console is blank
- INHIBITED indicator on line 25
INTERVENTION REQUIRED response to application
programs
All functions NORMAL when switched from OFF to
ON
No Power-On/IML.

Note: If the main console is in the OFF state, and the
Power-On/IML key is pressed, a message appears on the
screen of all unlocked and operational 3278-2A consoles on
the system indicating that the CHG DPLY key should be
pressed on the console from which the Power-On/IML is to
continue. The key is ignored if it is pressed on a console
with the security lock in the OFF position. However, if the
lock is turned to the ON position Bnd the CHG DPLY key is
pressed, the Power-On/IML will continue from that console.

,"

The computer program that you are working with also can
activate the. alarm. To do so, it sends a signal to your
display. The user's guide for that program will tell you if the
audible alarm will sound and, if so, the different reasons for
sounding it.
The volume of the audible alarm is adjustable. The
adjustment control is located at the outside of the screen
contrast control. Generally, it has been set for your operating
environment. To test the volume level, the next-to-Iast
character position must be in an unprotected input field. If
your display station does not have have an unprotected input
field in this area of the screen, check the application program
User's Guide or ask your supervisor for instructions to obtain
one. When you have an unprotected input field in this area
of this area of the screen, move the cursor and key in a
character in the next-to-Iast position on the screen: then,
listen to the level of the alarm. To check the sound level
again, press the backspace key and, then, a character key. If
the sound is not at the desired volume, adjust the alarm
control and test the sound level again. When the volume
setting is correct, press the ERASE INPUT key.

EC 379586 19Nov79

,

@ 'IBM

The audible alarm always sounds when you enter a
character into the next to last character position on your
screen. The cursor wraps from the last character position on
the screen after a character is keyed into that last position.
This is normal operation. If you key another character after
the cursor has wrapped, it will be entered into the first
character position on line 1 of your screen. In this situation,
you wouldn't want to key on line 1 because doing so would
destroy the data already displayed there. In this case, the
alarm is warning you.

ALTER IGNORED: An alter attempt was made, but the
machine is in a state (not a softstop, and so forth) that does
not permit the alter to occur, or you have changed the
SELECTION line on a full-screen alter.
Recovery: Press the STOP key to softstop the machine and
repeat the desired alter function.

CONFG DATA ERR: CONSOLES: The configuration of
the console defined on the diskette is not the same as in SP
storage.
Recovery: Ensure that proper diskette is installed and then
perform a SP-IML.

CONFG DATA ERR: UCWS: The number of UCWs
defined on the diskette is not the same as in SP storage.
Recovery: Ensure that proper diskette is installed and then
perform a SP-IML.

ALTER WILL BE IGNORED: An attempt to alter data on
ACB VALUE CHANGED BY XXK: Assigned UCWs take
a reserved storage area of 128 UCWs. After this boundary is
passed, each block of 32 UCWs takes an extra 2K of user
storage. This change is reflected in the Address Check
Boundary generated at the next IML.
ADDR COMP REMAINS: An address-compare match is
still waiting to occur even though you issued the OBH
command.
Recovery: To set the address compare to normal, enter QAN.

ADDR CUU ALREADY ASSIGNED: The address
assigned in the Tn or Hn command was assigned to a
non-native device via the UCW assignment screen.
Recovery: Assign the device (Tn or Hn) to an unused address.

or too low; or the address is larger than the physical storage
size.

the current screen was ignored. because the current screen
remains displayed after a successful fast-selection operation
on another screen.
Recovery: Pressing the ENTER key restores normal operation
back to the displayed screen.

BLOCK IS AT MATCH-WAIT: A block is running and is
at a Match command waiting for an address compare.
Another block or patch must not be activated at this time.
Recovery: To halt the block enter OBH.

CE LOG MUST HAVE A TITLE: A title must be entered
to have the log displayed in the index.
Recovery: Enter a title name in Log Title (Log 1/).

CHANGES REQUIRE IML: A change to console mode or
console address was made, but could not be communicated
to the processor.
This message also appears on the Mode Assist screen (OLI)
if any changes to the fields are made.
Recovery: To put the changes into effect, re-IML.

CHANNEL 0 UNAVAILABLE: A function requires the
local channel path (channel 0) between the SP and the PU,
and that path is busy with a PU operation.

Recovery: Enter the correct address parameter.

ADDRESS TOO LARGE: Address specified is beyond
what is allowed.
Recovery: Correct the ADDR parameter and re-enter the
function.

Recovery: Retry the function. If the message continues to
display, press the STOP key. A SP re-IML may be needed to
clear a channel program loop to the operator's console, or a
program reset may be required to clear a channel program
loop to channel O. A program reset under these
circumstances takes longer to complete than normal.

CONS PTR NOT CONFIGURED The console printer is
not configured at the Program Load (OL) screen.
Recovery: Configure the Copy key to a console printer on the
Program Load screen. Typically the console printer is set to
KO. A K 1, K2, or K3 must be entered depending on which
native device is the printer. The command must then be
repeated.

CONV-CHECK: The color convergence of the console

DATA BANK MODE ACTIVE: Remote Data Bank mode
initiated. All PU operations are terminated and the SP acts
like a 3275. When Data Bank mode is terminated, power off
and then on.
DATA LINK DISCONNECTED: The DISC key was
pressed, and all remote service was terminated.
DATA NOT ACCESSIBLE: The virtual storage address is
not available to the display / alter function or the UCW data
could not be accessed at this time because the processor is
busy.
Recovery: This virtual address cannot be used in the
display / alter function at this time. Change the address, retry
later, or discontinue the attempt to display / alter. If UCW
data cannot be accessed now, retry later.

DATA NOT ON TAPE: The diskette image is not found on
the tape.

CONSOLE DISK FAILURE: Ten errors occurred on the
same record on the disk during IML. This error may be
accompanied by a reference code.
Recovery: If failure persists or is accompanied by a reference
code, go to Start MAPs.

CONSOLE DISK I/O ERROR: An error occurred during
an attempt to read a program from the disk. This error may
be accompanied by a reference code.
Recovery: Go to the Start MAPs.

CONTROL STORAGE FAILURE:
•

The control storage failed during IML.

•

Interval Timer Switch (J)
Interval Timer switch has no additional display.

2. Press ENTER.
The interval timer function is available when the system is
operating in 370 or VSE mode. The Interval Timer switch is
automatically set on when the system is IMLed. The timer
can be turned off by entering a J following the SELECTION
label and pressing ENTER on the keyboard. Whenever the
switch is on, TIMER: ON is indicated on line 21 of the display
console. Whenever the switch is off, TIMER: OFF is
indicated on line 21.

The cursor is next to SELECTION: and ready for input. To
select one of the functions:

Note: The appropriate action is carried out as soon as
ENTER is pressed for characters Y, J, PROGR, CLEAR, CM,
RES, SAVE and Z.

The clock can be altered by the Set Clock instruction. After
pressing the ENTER key, screen control is immediately
switched to the Operating System screen.
TOO: ENBL is indicated on line 22 of the display console
for approximately six seconds, and then the TOO is
automatically disabled.

1. Key in J next to the SELECTION label.

Selecting a Manual Function

Another display appears on the screen if you made a
selection that appears to the right of the screen. This new
display usually requires the same action as above, that is,
selection of a displayed character, arid then pressing ENTER.

2. Press ENTER.

STORE STATUS

When CHG DPLY is pressed (if last screen displayed in
manual mode).

1. Key in the selector character shown on the left of the
required operation.

1. Key in Y following the SELECTION label.

Once you are familiar with the manual selections, selector
characters, subsequent displays and their associated
parameters, you can execute a function in one step. This
feature can be implemented from most manual selection
screens. One fast-select method is the execution of a
manual function directly from the General Selection screen. A
second way is to switch between manual functions, and
directly execute the function just selected. To initiate fast
selection, the letter Q must always proceed the function being
implemented.

To perform fast selection:
1. Press MODE SEL (if system screen is present).
2. Press Q.
3. Key in character that represents manual function you want
to perform.

The interval timer is alternately turned on or off each time
that a J is entered.
When the timer is activated, real main storage location 80 is
decremented approximately every 30 ms. When the location
goes negative, an interrupt is generated. If the timer is off,
location 80 is available for use.

4. Key in parameters for the manual function you have just
selected.
5. Press ENTER.
Note: Do not insert commas between characters. If the
system finds a syntax error, the screen that represents the
last correct letter is displayed. The manual functions
compress the selection line input and ignore blanks entered
into the system.

Program Reset (PROGR)
Clear Reset (CLEAR)
Note: If a Clear Reset is performed while a trace or
stop-on-main-storage-data-compare (nonzero) funct/,m is in
effect, a false match stop occurs.

Check Reset (Re-IML)

Restart (RES)

Store Status (SAVE) (370 Mode Only)

The only reliable way of clearing an intermittent check is to
re-IML the processing unit. This command is QLM. If
another checkstop occurs, the error is probably not
intermittent. However, most checks can be cleared either by
the Program Reset (OPROGR) or Clear Reset (QCLEAR).

RESTART has no additional display.

This function stores in hex and is allowed when running with
Virtual Storage Control. STORE STATUS has no additional
display.

Machine Reset (CM) (Normal)

There is no display for Program Reset or Clear Reset.
1. Key in either PROGR (Reset-Program) or CLEAR
(Reset-Clear) following the SELECTION label.

The Machine Reset is a CE-only function to be used when
directed by your FSC or Product Engineer.
To invoke the Machine Reset function from the General
Selection screen:

2. Press ENTER.
Keying in either PROGR OR CLEAR and then pressing
ENTER:
•

Clears pending interrupts or machine check conditions.

•

Causes the following to stop:
Execution of the present PU instruction (if any)
All channels and their control units
All adapters
All I/O devices (channel and natively attached)
Resets manual functions
Time-of-Day Enable
Save Indicator
Operation Control Rate (except I-step)

•

•
•

•

1. Key in SAVE following the SELECTION label.

If the machine is in stopped state, it starts with the program
restart PSW. If the machine is in the operating state, the
PSW exchange occurs at the end of the current instruction
after all interrupts for which the PU is enabled are handled.
To return the console to the operating system:
Press CHG DPLY or,
Key Z next to SELECTION and press ENTER.

The following are stored in main (real) storage:
• Processor timer -

8 bytes at '08' (216 dec.)

• Clock Comparator -

8 bytes at 'EO' (224 dec.)

• The current PSW -

8 bytes at '100' (256 dec.)
32 bytes at '160' (352 dec.)

• General registers -

64 bytes at '180' (384 dec.)

2. Press ENTER.

• Control registers -

64 bytes at '1 CO' (448 dec.)

Note: The following happens:
•

Machine Save (SAVE) (VSE Mode only)

All scan rings are reset including those related to the
clocks.

In VSE mode, the Save function is called Machine Save. This
function saves the above data as well as page 0 (virtual
address 0 to 2048) in auxiliary storage for subsequent
retrieval by a Retrieve Status and Page software instruction
(08).

The refresh clock is turned on at the end of the routine.
CAUTION Because the Refresh Clock is stopped,
double-bit errors occur in main storage.

•

When Store Status or Machine Save is complete, SAVE is
indicated on line 21 of the display console, and the system
goes into a stopped state.

Use the PU microcode.
Clear or reset any arrays.

Page management pointer (VSE mode)

2. Press ENTER

OCMrr resets specified scan rings. rr is the specified ring to
be reset. In general, operational results are unpredictable.

The screen is under control of the operating system.
Note: The support processor transient area is released and
the contents of the system mode (usually operating system
messages) buffer is displayed.

With Log

QCMLxxxx resets machine latches from a specified machine
check logout. xxxx is the same four digits as those specified
to display the detailed error logout (OECDxxxx). The machine
is placed in CK-CTRL=HARDSTOP automatically. All
nonarray Insert/Extract screens may now be used.

Note: Pressing the POWER ON /IML switch (with power up)
does not reset the processor. Only the SP code is reloaded
and normal processor operation can be continued. This
switch clears up Channel 0 if it has failed due to an
intermittent problem. The Reset button (logic reset) on the
main frame near the diskette drive is similar to the SP
re-IML, but no SP code is reloaded.

CONSOLE COLOR CONVERGENCE (QFA)

Convergence Procedure

CONVERGENCE UTILITY

The Console Color Convergence screen is used to align the
color on a color display console. The initial display when
making this selection is a description of the operation of the
convergence procedure.

To return to the General Selection (0) screen, press the
MODE SEL key. However, because of interaction of some of
the convergence positions, check all positions after the
procedure is started. It is not necessary to adjust each
position; advancing through each pattern position with the
SPACE BAR performs the necessary action.

•

After all thirteen positions have been adjusted, the
pattern displays white in all positions (see test pattern
diagram). This is the final check for convergence.

Use the convergence procedure when setting up a color
console, when the console has been moved to another area,
or when color definition is in question.

ENTER INITIALIZES UTILITY (MUST BE PRESSED 1ST)

Convergence can be adjusted by using the keyboard to
manually align a pattern. By using two colors (red/green or
red/blue), a pattern (-1-1-) is displayed at a location on the
screen, any misconvergence can be easily seen. In a correctly
converged screen, the two colors combine to show one
pattern, in the color obtained by mixing the two primary
colors (red/green combine into yellow, and red/blue combine
into pink). A misconverged screen shQws traces of the
primary colors at the edge of the pattern or, if the
convergence is bad, two separate patterns. The pattern is
displayed at thirteen positions on the screen to allow all areas
to be converged. At each of the thirteen positions, the
pattern is first displayed in red/green, .and then in red/blue.

CURSOR UP, DOWN, LEFT, OR RIGHT MOVES THE PATTERN
SPACE BAR SELECTS NEXT POSITION OR COLOR

Notes:
If INHIBITED or any other symbol appears in the
operator information area, press RESET and retry the
action.

The convergence procedure is used to optimize the 3279-2C
color console primary color settings (red, green, and blue) to
produce a pure compound color (white). If convergence is
wrong, traces of each color are displayed at the edges of the
white character.

THIS UTILITY IS USED TO CONVERGE RED, GREEN, AND BLUE
DISPLAYS INTO CORRECT ALIGNMENT.
PATTERNS ARE SHOWN
TWICE AT 13 POSITIONS ON THE SCREEN, IN RED/GREEN AND
THEN RED/BLUE. THE 4 CURSOR KEYS ARE USED TO MOVE THE
2 COLOR PATTERNS TOGETHER INTO I COLOR, THE RED/GREEN
MERGES INTO YELLOW AND RED/BLUE MERGES INTO PINK.

Pressing the ENTER key advances the screen to the pattern
display to start the adjustment. The ENTER key may be
pressed at any time to restart the adjustment.

•

R KEY CHANGES PATTERN COLOR (RED/GREEN(-)REDBLUE)
MODE SEL KEY EXITS UTILITY

The cur!ilor positioning keys move the green (or blue) pattern
towards the red until they coincide and a yellow (or pink)
pattern is displayed. These keys are typematic and can be
held down until the pattern is in the correct position.

The convergence procedure cannot be directed to another
console. You must be physically at that console and in
manual mode to perform the procedure.

To select the Console Color Convergence screen from the
Configuration screen:

1. Key A next to F on the SELECTION line.
2. Press ENTER.

The "R" key is used to reverse the color setting of the
displayed pattern (red/green to or from red/blue). This
allows the pattern to checked and adjusted at one position.
Use he SPACE BAR to advance to the next adjustment
position in the convergence procedure. The initial pattern at
each position is displayed with the red/green colors.
Pressing the SPACE BAR at this time changes the pattern to
red/blue (the same as the "R" key). Pressing the SPACE
BAR when the red/blue pattern is displayed advances the
procedure to the next adjustment position, and displays the
pattern in red/green. After the la.st position has been
adjusted, pressing the SPACE BAR displays the pattern in
white at all positions. If the SPACE BAR is pressed again,
the procedure restarts at position one.

MODULE TRANSFER (QFM)
The Module Transfer screen moves the machine-dependent
data module from one support processor diskette to another.
When the EC is ready to be installed; take a stock EC disk to
be updated with the data from the disk already there. The
new disk then is unique for this particular system. Patches
and Assists can not be transferred by the Module Transfer
screen.
The Module Transfer screen has two different input areas:
the first is the area to the left of the module of MACHINE
SENSITIVE DATA, and the other is for entering instruction
type on the SELECTION line. The first area of input is on the
full-screen area. The only inputs that are valid are "X" or
"
"(or blanks). For any other input, an INVALID message
appears. The second area of input is through the normal
manual function input that is on the SELECTION line. These
commands are displayed on the screen.
The module IDs are shown for each line and are taken from
the disk that contains the Module Transfer CODE. If the two
disks do not have the same module IDs, the transfer does not
occur.
The first selection is special in that only part of the total
module shown is transferred. For the configuration data, the
information unique to a disk (such as part number and EC
number) is not transferred. For the reset data, only those bits
that are machine sensitive are transferred to the reset data
module.
The Status Area of the Module Transfer screen shows the
current status of the transfer taking place. The status area
has four positions. The first shows the state of the transfer:
S - selected for transfer; R - read from the disk and store
either in main storage or in the support processor buffer; W write on the disk from the storage area; T - the module has
been transferred completely. The second through fourth
positions show any error that has occurred during a read or
write portion of the transfer. The "0" is followed by an error
indication.

COMMANDS:
SELECTION: M

(/

The transfer is completed regardless of the command
used, size errors, or load address errors. However, the
module in error is flagged as an error module and is not
used again.
Once the transfer is started, the microcode asks for the
FROM disk. This allows you to use a different disk for
the FROM modules.

S=SELECT R=READ & SAVE W=RETRIEVE & WRITE T=TRANSFER COMPLETE
DSZ=SIZE DIFFERENT DLA=LOAD ADDRESS DIFFERENT D41=NOT FOUND
INVP=INVALID INPUT
MSTARTL
MSTARTD

(

STARTO only requires the support processor and uses a
buffer of about 4K. If no selection errors occur, the code
transfers modules from the disk to the buffer. You are
then asked to swap the disks. The modules are then
transferred from the buffer to the new disk. You are then
asked to swap back to the old disk. The transfer then
continues until all of the modules selected are transferred.

To invoke the Module Transfer screen:
Warning: Do not press the Copy key during a' Module
Transfer; the transfer is not completed. If a transfer is
desired, rekey the previous command.

1. Place the CE MODE switch ON if you have not already
done so. If you have not, you must select the
Configuration screen first.
2. Key M on the SELECTION line.
3. Press ENTER.

4. After the Module Transfer screen is displayed, move the
cursor to the module(s) that you do not want to transfer
and place an
next to that module. Ensure that an X is
next to the module(s) that you do want transferred.

5. Press ENTER. The status area displays an S beside those
modules which you have selected.
Note: If an error occurs, INVP is displayed instead of S.

6. Key STARTL or ST ARTD next to the M on the
SELECTION line, depending upon the type of transfer you
wish to do.
STARTL requires the processing unit to have been
IMLed but not IPLed.
Warning: If the machine has been IPLed, a QCLEAR is
required. However, a loss of customer data can result
with this selection.
If no error occurs, the code transfers modules from the
disk to the processor main storage, and asks you to swap
disks. After the disk has been swapped, the modules
from the processor storage are transferred to the new
disk. One disk swap transfers all modules. The request
for the ORIGINAL disk indicates that the transfer is
complete. If a support processor-processing unit
interface error occurs, the process stops, and the transfer
must be restarted.

PROGRAM lOAD (Ql)
The Program Load screen is the console function which
controls the processing unit (PU) initial microcode load (lML)
and the system initial program load (lPL). This screen can be
invoked automatically from initial power-up or selected from
the General Selection screen (0).
The System operates in two modes. One is the System/370
(S/370) emulate mode. The other is the Virtual Storage
Extended (VSE) mode and is the normal 4300 mode. The
parameters that have been set determine the mode that is
invoked automatically at power-up.
A function of the Program Load screen is to display the
optional parameters. This function is similar to a
configuration function because the parameters are changed
and the configuration record is updated. The selected
parameters are intensified on the screen.
From the Program Load screen you can go to the Mode
Assist (I) screen, the General Selection (0) screen, or Return
to Programming Systems (Z) screen.

. Entering L on the SELECTION line returns the display to the
Program Load screen. If another screen is displayed from the
Model Assist Selection screen, any changes made to the
mode and assist fields are lost and the previous settings are
loaded when the processor is IMLed.

A function of the Program Load screen is displaying the
optional parameters. This function is similar to a
configuration function because the parameters are changed
and the configuration record is updated. The selected
parameters are intensified on the screen. Anyone or all of
the commands with parameters can occur in any order on the

Entering M on the SELECTION line returns the display to the
Program Load screen and initiates the microcode. load that
was last specified on the Model Assist Selection screen.

Perform IMl 1M)

General Selection (a)

Keying M next to SELECTION and pressing ENTER IMLs the
processor and loads the microcode for the mode selected on
the Model Assist screen.

Entering a Q on the SELECTION line changes the display to
the General Selection screen. If this screen is displayed from
the Model Assist Selection screen, any changes to the mode
and assist fields are lost. You must perform an IML to carry
over the new mode and assist selected for 1M L.

IMl at Power-On (Xn)

Return to Prog Sys (Z)
)

The following describes the Program Load screen
parameters:

Entering a Z on the SELECTION line returns the display to the
Operating System (Display or PtrlKybd mode) screen. If this
screen is displayed from the Model Assist Selection screen,
any changes to the mode and assist fields are lost. You must
perform an IML to carry over the new mode and assist
selected for 1M L.

Power-on IML can occur only when the support processor is
IMLed from a power-off condition, the CE/NORMAL switch
is in NORMAL, and X1 has been previously selected. If the
first screen is other than the Program Load screen, no
automatic IML is performed regardless of the parameter
setting. For an automatic power-on IML, key in X1 next to
SELECTION. For no automatic Power-On IML, key in X2.

Reset Type (Rn)

The following shows the effect for an IML function.

This parameter specifies the type of system reset taken. The
reset is the one currently intensified on the screen. The reset
type can be changed by entering the appropriate code (R1 or
R2) following the SELECTION label and pressing ENTER.
Once selected, the load clear (R 1) reset function remains
active (intensified) only until a successful IPL is accomplished.
A successful IPL or power-off changes the selection back
to load normal (R2) reset function.
At IPL time, a basic processor and an I/O system reset in
the configured channels is performed. As part of the I/O
system reset. pending interrupts are cleared, and a system
reset is signaled to the I/O control units and devices
configured to the channel.
The first IML from power-off resets the entire processor.
Subsequent IMLs reset everything except the TOO clock.
When in VSE mode, and a re-IPL is being done with the
RESET -NORMAL selected, there must be enough
addressable virtual storage to load and initialize the
program/system. If not, the program can be designed to
detect the program check and issue VSE instructions to
obtain more addressable virtual storage. This is required for a
stand-alone dump when RESET -NORMAL is selected.
If neither of these two options is available, the IPL must be
performed with RESET -CLEAR selected.

Notes:
•

If you select IML at power-on, do not perform any other
function or press any key until the power-on and IML
functions are complete. These functions cannot be
aborted because microcode is involved in a very complex
sequence.

Console Mode (Nn)

Copy Key (Kx)

Note: You must softstop the machine (press the STOP key)
before changing this parameter.

The COPY KEY is displayed on the screen to indicate the
assignment of the COPY key. The three modes of
assignment are:

The N command allows the assignment of consoles to either
printer/keyboard or display mode. If an N1 command is
assigned, all consoles are assigned to the printer /keyboard
mode, which provides the channel interface for 1052/3210
type of devices. This mode permits the optional coupling of
a display console with a printer as a one-device address. To
couple, assign the devices (display and printer) the same
console address. Data that is on the display console is
automatically printed on the printer when these devices are
coupled together.
When in printer/keyboard mode (N1), a maximum of two
addresses can be assigned regardless of the number of
terminals attached. The maximum configuration in
printer/keyboard mode is two display consoles coupled with
two printers. Any over two display consoles attached to the
system must be disconnected (DSC). A printer cannot be
assigned a console address without being coupled to a
display console. An error message occurs if these restrictions
are not observed.
If an N2 command is assigned, all consoles are assigned to
the display mode, which enables the channel interface for
. 3270-type of devices. This mode requires each device to
have a unique device address - no sharing of addresses.
This address has either a T or H device assignment with its
accompanying unit number.
Note: When changing between Display and
Printer/Keyboard modes, key both console mode and
address changes as one entry (for example: NT TOO ToH3o TO).

Console Address (Tn/Hn)
Note: You must softstop the machine (press the STOP key)
before making a change to this parameter.
A terminal that is attached to the system causes a Tn or Hn
to be displayed on the Program Load screen. The "T"
designation indicates a display console; an "H" indicates a
printer. The number "n" following the T or the H indicates
the port to which the device is attached. Each attached
terminal may be aSSigned a unit address if it is to be
accessed by the programming system. The unit address must
indicate channel zero (first digit is A), and the unit portion
must be an unassigned address on this channel.

Channel Printer (KC cuu)
The Program Load screen highlights the current selection. It
displays only those devices physically attached and selected
as installed on the System Configuration screen (QFS) or, if a
channel-attached device, on the UCW Assignment (QDU)
screen.

•

Any terminal may be assigned an address of "DSC" (for
disconnected). A terminal that is disconnected has no
address and is not available to the programming system.
Assignment of terminal addresses depends upon the
console mode (display or printer/keyboard).

IML Invoke Procedure (M)

1. Key the parameters sequentially (any order) next to
SELECTION. Only those which require a change need to
be entered.
2. Key M next to SELECTION.
Note: This is necessary, to initiate the IML sequence,
even if the parameters have not been changed.

To invoke IML from a power-off condition:

The existing status of that screen can be later viewed by
using the Saved Screens (QEW) function.

Channel Printer (KC cuu): When the COpy KEY DEVICE
is configured for channel printer mode (KC cuu), the current
screen is printed by the assigned channel printer when the
COpy key is pressed.
Notes:
The Channel Printer (KC cuu) selection is operative when
the machine has been IMLed but not IPLed.
•

Pressing the Paging key while using the Diskette (KD) or
Channel Printer (KC cuu) options may require you to
press the key twice after using the Copy key function.

Fast-Select JML/IPL (MP)

1. Key MP next to SELECTION.
2. Press ENTER.

Warning: For the Diskette (KD) and Channel Printer IKC
cuu) options:
Before pressing the COpy key, wait until the input data
is saved. Input data is saved by pressing the ENTER key
after you have altered a screen. If you press the COpy
key before the input data is saved, the input data can be
lost.

Diskette (KD): When the COPY KEY DEVICE is configured
for Diskette mode (KD), the current screen is copied onto the
diskette when the COpy key is pressed.

To invoke IML from the Program Load screen:

3. Press ENTER.

For the Channel Printer IKC cuu) option:
If the machine has been IPLed, a QCLEAR is required.
However, a loss of customer data can result with this
selection.

(

To invoke IML and IPL from the Program Load screen:

Console Printer (Kn): When the COpy KEY DEVICE is
configured for console printer mode (Kn), the screen indicates
which console unit (not console address) has been assigned
to print the hard copy when the COPY key is pressed. If you
choose to remove the hard-copy device, key KO on the
SELECTION line and, if no other changes, press ENTER. For
example, if you want to assign a hard-copy device, key in K3
on the SELECTION line and press ENTER.

Notes:
Console addresses cannot be assigned with the
UCU/Device Directory Update function (QDUU).

Invoking Procedures

Console Printer (Kn)
Diskette (KD)

(-

(

Note: If there are no errors, all command parameters are
examined and executed, followed by an IML of the mode
determined by the parameters.

IML Invoke Procedure (Automatic)

1. Place CE MODE switch in NORMAL.

Notes:
Either M or P may be entered first, but IML always
executes before IPL.

If P is keyed alone without a prior IML, an error occurs.
IML executes with the existing parameter setting.

Fast-Select IML/IPL (Alternate) (QLM)
To invoke IML or IPL from any screen:
1. Key QL next to SELECTION followed by any commands
and parameters that may be required.
2. Key M or MP next to QL on the SELECTION line.
3. Press ENTER.
Notes:

2. Press POWER ON/IML.

All syntax and dependent error conditions are verified
and then executed.

Notes:

When the commands are complete, the system returns to
the Program Load screen and awaits further commands.

The parameters must have been set during some
previous power-up.
•

Support processor powers up.

•

Support processor does an SP-IML.

•

Processing unit powers up.

•

Processing unit does an IML.
Message NO IML, IML IN PROGRESS, IML ERROR, or
IML COMPLETE is displayed.

Invoking Conditions
Commands are examined for syntax errors (correct
parameters) first. Dependent commands are examined
next. An error in either place returns control of the
Program Load screen to the user. Only after all errors
have been corrected are the commands executed.
An IML is performed any time M appears on the
SELECTION line and there are no errors.

IPL Invoke Procedure (P)
To invoke IPL from the Program Load screen:
1. Key the parameters sequentially (any order) next to
SELECTION.
Note: Only those parameters that require a change need
to be entered.
2. Key P next to SELECTION.
Note: Examine the IPL Unit and IPL Reset type and key
in any corrections that may be required.
3. Press ENTER.

Screen data can be changed only by way of the
SELECTION line.
Internal errors (logic or hardware) are indicated by
reference codes.
If IML or IPL detects an error, a message is displayed,
control returns to the program load screen, and more
commands can be entered.
A SIGP instruction is used to change the console mode or
device address in the processing unit, provided the
processor is in a softstop state, not running or
hardstopped.

Notes:
Processing unit executes IPL and displays the message
IPL COMPLETE.

If P is keyed alone without a prior IML, an error occurs.

Patches at IML

Verification Tests (Vn)

No Control Store Load (V)

.coreloads in the processing unit can be Patched after every
IML. The patch is accomplished by invoking a Block. This is
a feature of the Block screen (QB). For procedures, see
"Block Facility."
,

Verification Tests are used only when directed by your
Support Structure. At IML time, four tests can be run that
ensure the proper operation of the component selected.

This command causes the livlL routine to skip the actual
loading of control storage.

To set up a patch, enter a block into the system with the
Block editing commands. (The Block must not contain
'ODD .. : commands that permanently alter the machine.)
Next, place the name beside the coreload to be patched in
the IML Patches screen (QBM). From now until the name is
removed from the QBM screen for the coreload IMLed, the
user is prompted with the question RUN PATCHES (Y /N)?
after every successful 1M L. The status of the invoked block
is displayed in the message area on line 20. If an error
occurs, control is returned to the Program Load screen, and
the status display is changed to PATCH ERROR.

The following commands are available and displayed only
when the CE MODE switch is ON.
Valid Arguments/Commands
V 1 - Control store test
V 2 - Data test of main store
V 3 - Address test of main store
V 4 - Scope loop test
To exit from any of these commands, press Program
Function key 9.

Save Storage (S)

Note: Errors occurring during IML cannot be patched with
this method because a patch depends upon a successfullML.

This selection reduces the resets done during a re-IML if the
coreload has not changed. Some of the arrays are not reset
and main storage is not cleared.

Action Parameters
Note: Each of the following action parameters show what
applicable selections can be made and what address
parameter is required to make the selection valid.

N NORMAL
When this function is selected, the Compare/Trace area is
cleared on line 22.
This action parameter is used alone to reset any 'previously
selected compare/trace functions. Keying N when on the
Compare/Trace screen or QAN from any other manual mode
screen terminates any compare/trace function, and normal
processing continues.

T TRACE-STOP
When this function is selected, ADDR-COMP: TRST appears
on line 22.
On a Type C (lnstr Counter) operation, this action causes
the instruction counter addresses to be stored in a trace area
until the trace area becomes full (128 addresses). When the
machine is stopped because the trace area is full, MATCH
STOP (INSTRUCTION STOP if tracing a instruction) is
displayed on line 21. Pressing the START key repeats the
process.
On Type A, 0, and I operations, the instruction counter
address is stored only when the compare conditions specified
by the remaining parameter fields are met. Processing
continues following each compare until the trace area is full.

Following a successful compare, the current microword is
completed, and no additional microwords are executed.
(Refresh clocks continue to run.) MATCH-STOP appears on
line 21. Hard stop is implied when CSAR is displayed on line
21.
•

Following a successful compare, the system generates a
sync signal. This sync signal can be monitored at A2J4G03.
The system does not stop.

In this mode, the CSARBU trace array contains the address
of the last 32 targets of microwords that caused a modular
switch. The addresses can be monitored by displaying this
array by the Insert/Extract function aVAB.

On a Type C (lnstr Counted operation, this action causes
the instruction counter addresses to be stored into the trace
area. When the trace area becomes full, additional addresses
are stored, and the oldest are dropped so that the trace area
always contains the 128 most recent addresses.
On Type A. D, and I operations, the instruction counter
address is stored in the trace area only when the compare
conditions specified by the remaining parameter fields are
met. Processing continues following each compare.

The microword that caused the match is at the control
storage address last entered into the trace array (aVAS).
This address is the one logically preceding the address

M MICROWORD

X CHANNEL-DATA

OP Field

DATA Field

The microword-type function can be selected only when the
CE MODE switch is on. When selected, TYPE: MICWRD
appears on line 22.

The channel data function can be selected only when the CE
MODE switch is on. When selected, TYPE: CH-DAT appears
on line 22.

This field is used for address type or data compare
operations.

This field specifies up to two bytes of data to' be compared at
the address specified in the ADDR field. Any hexadecimal
digit or digits comprising the two-byte data compare field can
be ignored by entering a period (.) as a "don't care"
character.

The control storage address backup (CSARBU) contains the
address of the microword currently being executed. The
. address specified in the AODR field is loaded into the control
storage address match register. When the CSARBU register
" and the CS address match register compare, a signal
indicates a control storage match.
If a hard-stop action is selected and a match occurs,
MATCH STOP appears on line 21. The match address
appears in line 21 opposite the CSAR label. The S (Stop)
selection is also allowed.

This function provides a hard stop or a sync pulse on a
specific byte of channel data by specifying the channel
number and byte of data. The type must follow the format:
cdd
where:
c
Channel number
dd = One byte of hex data

The destination address specified in the ADDR field is
loaded into the local storage address match register. When
this register compares with the local storage address register,
and data is written in that local storage element. a signal
. indicates a local store-destination address match.
If a stop action is selected and a match occurs, MATCH
STOP appears on line 21. The match address appears on line
22.

ADDR Field

The address field is displayed on line 22 provided a data
compare operation is not in process. This field is used to
enter the search address for all compare/trace functions.
The characteristics for the address specified are:
•

The search address can be up to a six-digit hexadecimal
number.

•

The maximum address value must be less than the
machine capability. Five maximum values are checked:
physical real main storage, customer accessible real main
storage, virtual main storage, control storage, and local
storage.
The address specified in the command is always
converted to the next lowest doubleword (S byte)
boundary because the machine accesses eight bytes of
storage simultaneouly. A compare occurs, if the address
specified in a storage operation is anywhere within this
doubleword.

The local store-source function can be selected only when
the CE MODE switch is on. When selected, TYPE: LS-SRC
appears on line 22.
The source address specified in the ADDR field is loaded
into the local storage address match register. When this
register compares with the local storage address register and
data is read in that local storage element, a signal indicates a
local storage source address match.

Note: The following restrictions apply to data compare
operations.
.

In 370 and VSE (CE only) mode, if data is not to be
specified in the DATA field, enter a V or R in the OP field to
indicate whether the previous address specified in the ADDR
field is a virtual or real storage address. If V or R is not
specified, a default is assumed based on the mode selected.

O-FFFFFF

•

S LOCAL STORE-SRC

For bit compare operations (& or % in OP field), only the
bits that are on to comprise each hexadecimal digit are tested
for an equal (on) or not-equal (off) condition. For example, if
the data compare field contained the. digit "3" (bits = 0011),
all digits containing the last two bits equal to "1" (such as 7,
bits = 0111) compare equal. All other digits compare on a
not-equal operation.

In VSE (NORM only) mode, if data is not to be specified in
the DATA field, the OP field is not used.

L LOCAL STORE-DST
The local store-destination function can be selected only
when the CE MODE switch is on. When selected, TYPE:
LS-DES appears on line 22.

In VSE or 370 mode, this field is used when compare data
is to be specified in addition to an address. The options are
to compare the data specified in the DATA field for an equal
or not-equal condition on any Type A, 0, and.1 operations.
On Type C operations, data can be compared only when
using the STOP function. Data compare is not allowed on a
Type C operation for trace-stop (T) and trace-wrap (WI
functions.

Data compare operations beginning on the last byte of a
2K page are not allowed.

The field equal (=) option compares up to four hexadecimal
digits (two bytes) of data specified in the DATA field for an
equal condition.

•

On Type A, D, and I operations, miSSing a data compare
is possible if sequential instructions change the same
two bytes of storage.

•

If a Clear Reset (see General Selection Screen) is
performed while a trace or a stop-on-main-storage data
compare (nonzero) function is in effect, a false match
stop occurs.

•

Data Contents Compare is performed by microcode and
allows compares down to the halfword or bit. However,
because the basic match hardware stops if a reference is
made to a doubleword, the data in the target address
may not actually have been referenced.

The field not-equal (I) option compares up to four
hexadecimal digits (two bytes) of data specified in the DATA
field for a not-equal condition .
The bit equal (&) option compares all of the bits of the data
specified in the DATA field for an equal (on) condition.
The bit not-equal (%) option compares any of the bits of
the data specified in the DATA field for a not-equal (off)
condition.

V /R Field (370 Mode only)
This field is used only in 370 or CE mode when the DATA
field is specified to indicate whether the address contained in
the ADDR field is a virtual (V) or real (R) address.

Example:
Main storage must be 2080 not 208 for 2080- 7.
Local storage must be 3FO not 3F for 3FO-7.

If a stop action is selected and a match occurs, MATCH
STOP appears on line 21. The match address appears on line

CHECK CONTROL (OK)
The Check Control screen enables selecting the action to be
taken by the PU when an interrupt occurs because of a
machine check. MACHINE CHECK is indicated on line 21.
Functions N, S, R, and D are mutually exclusive; functions C
and H are independent. In CE mode, an additional selection
list allows the service representative to halt SP functions that
may interfere with testing and debugging. If one of the
functions has been fast-selected, the current screen remains
displayed with the last command entered redisplayed on the
SELECTION line in a fast-select format.
If any of the high-level checkers are turned on by a
malfunction, an error latch is set, and the processor clock is
stopped. The support processor continually monitors the
status of the processor. Whenever the clock is stopped, the
support processor posts a machine check and examines the
check latches and other facilities to determine if the
instruction is retriable. If the instruction is retriable, the
support processor retries and then logs the machine check to
the disk. If the retry is successful, the log counters are
updated and processing continues. If the retry is
unsuccessful or the instruction is unretriable, the support
processor posts check stop on the screen. After the analysis
is completed. the support processor invokes the proper
routines to generate a reference code, and the system
remains in the check-stop state. At this time, the reference
code is posted both on the disk and on the screen.

DISPLAY/ALTER SCREENS

DISPLAY/ALTER (D-SCREEN)
The display/alter function lists a menu that can be invoked by
selecting the D-screen. Most display/alter functions use the
local channel adapter to transfer data to and from the
hardware. Because most display/alter functions use the LCA,
the machine must not be hard-stopped for most of the
display / alter code to run. The function list is redisplayed each
time a new function is selected. As a result, the output area
is cleared for the next function.
Selections S, A. U, L. X, W, and 0 are not selectable on the

customer screen.
The two ways to select a screen are: key a character next
to the character on the SELECTION line (a subscreen is called
up). or key a and the facility or facility with its subscreen. For
example, aDL bypasses the General Selection and bypasses
the Display/Alter screen and displays the Local Storage

subscreen.
The alter function and the display screens are much the
same. The full-screen data can be chang~ by using the
cursor and rekeying data, but the characters on the
SELECTION line must be unchanged. In full-screen altering,
blanks, hex zeroes, and periods are "don't care" characters.
For Fast Select Alter, the period is a "don't care" character.
The hex zeroes and blanks are compressed out (deleted) from
the SELECTION line when fast altering. On a full-screen
alter, the cursor moves to the first data position if an invalid
character is entered. On Fast Alter, the cursor moves to the
right of the op code if an invalid character is entered. Any
invalid character prevents an alter operation (full screen or
Fast SeIect).

DISPLAY/ALTER D-SCREEN (aD)
Most displays and alters can be performed by two means:
screen select and fast-screen select.
To select the Display/Alter screen from the General Selection
screen:
1. Key in 0 following the SELECTION label .
. 2. Press ENTER.
The display/alter image appears on the screen and the
program stops. The items listed on the screen show those
areas of the system that can be displayed and altered. You
can now select one of the set. After you have chosen a
display / alter function, the display/alter image remains on the
left portion of the screen, and the selected facility appears on
the right portion.

TRANSLATION
The translate function is applicable to many of the
display / alter functions. If you select the translate option, all
full-screen input areas are eliminated (alter- is inhibited), and
the function is in translate mode. You may now page the
data and it stays in translate mode. A command from the
SELECTION line without the translate op code restores the
screen input areas and allows full-screen alters.
To use the Translate op code, which converts hexadecimal
to EBCDIC character format:
1. Key the D / A function and parameters (if any) plus T.

2. Press ENTER.

DISPLAY/ALTER HEX CALCULATOR (00=)
The hex calculator function converts two hex addresses
arithmetically to one hex address. One address can be added
or subtracted with another. This function uses two operands
(0-6 digits) and can be defaulted to 000000. Both operands
remain a constant unless a new operand is rekeyed. The only
op codes are (+) and (-). Plus (+) adds the second operand
to the first operand. Minus (-) subtracts the second from the
first. An example is shown on the hex calculator function.
The result is displayed next to the message indicator.

Display Hex Calculator
To display the hex calculator function from any D-screen:

1. Key QD= next to SELECTION followed by:
(a) operand one (if any)
(b) op code (if any)
(c) operand two (if any)

2. Press ENTER.
Notes:
•

The operands and result are displayed next to the
message indicator.

•

The hex calculator function can be fast-selected from any
screen and that screen remains.

•

By keying 00=, the last calculation is restored on the
SELECTION line.

•

Each operand is retained until it is replaced; thus, either
can be used as a constant.

DISPLAY/ALTER VIRTUAL STORAGE 370/VSE
(QDV)

Display Virtual Storage 370/VSE
To select the virtual storage function from the O-screen:
1. Key V and the six-digit address next to SELECTION. The
address valueS are O-FFFFFF (hex). The address may be
defautted to zero.
2. Press ENTER. A 128-byte block of data containing the
selected address is displayed.

NOte: The lIirtuai storage address can be modified by
placing. (+) to add or a (-) to subtract from the address
ktl'!ed next to SELECTION. An example is shown on both
screens. When the Adjust Value has been entered, it
reinains until a new lIalue has been entered or you select
another screen that is not a Displll'l/Alter screen.
You can ktl'! in the Adjust Value alone or with an address.
No address entered defaults to zero. The data appeers in the
normlll area as though it were at the selected address, but
the data is actually that data located at the adjusted address,
evM though the address under label ADRS is that from the
address on the SELECTION line. You can key a new address
or USII the PAGE ktl'!, and you still get the data from the
adjusted address. The address plus the Adjusted Value
might cauSll the screen to heve a fwos-complement negatille
number.

Save Virtual Storage 370/VSE
Eight bytes of data in virtual storage, starting with the
address in the save area;can be saved by the Block function.
An example of how you can save the virtual storage data is
QDVxxxxxx7.
Note: You can use the 7 opcode to lIerify if data exists at
the address before altering that data. This feature is lIery
helpful while running a block, but it can be uSlld at any time.
After the 7, enter any number of digits for the data that
would be at that address. YOU can alter ·any number of digits
by also using an alter op code~ such as (=). If the data at
that address does not match, no alter occiJrs. If you halle no
match, and the data you are matching and the data which
you wish to alter match each other, no alter occurs, nor does
an error occur.

the address before altering that data. This feature is very
helpful while running a block, but it can be used at any
time. After the 7, enter any number of digits for the data
that would be at that address. You can alter any number of
digits by also using an alter op code, such as (=). If the data

no match, and the data you are matching and the data which
you wish to alter match each other, no alter occurs, nor does
an eFTor occur.

next to SELECTION. An example is shown on the aDV
screen. When the Adjust Value has been entered, it
remains until a new value has been entered or you select
another screen that is not a Disptay / Alter screen. You
can key in the Adjust Value alone or with an address.
No address entered defaults to zero.
The data appears in the normal area as though it were
at the selected address, but the data is actually that data
located at the adjusted address, even though the address
under label ADRS is that from the address on the
SELECTION line. You can key a new address or use the
PAGE key, and you still get the data from the adjusted
address. The address plus the Adjusted Value might

DISPLAY/ALTER SP STORAGE (QOW)

Display SP Storage
To select the SP Storage function from the D-screen:
1. Place the CE MODE switch ON.
2. Key Wand a four-digit address next to SELECTION. The
four digits represent an SP address and range from 0 to
FFFF. The address is defaulted to zero if no address is
entered.
3. Press ENTER. A 128-byte block of SP storage containing
the selected address is displayed.

Alter SP Storage
Notes:
•

There is no full-screen alter for SP Storage.

•

Data is shown and entered in hexadecimal.

•

The next higher/lower 128-byte boundary can be
displayed by using the paging keys.

•

The Translate option is applicable to the SP Storage
display.
The SP storage address can be modified by placing a (+j
to add or (-j to subtract from the address keyed next to
SELECTION. An example is shown on the aDV screen.
When the Adjust Value has been entered, it remains until
a new value is entered or you select another screen thai is
not a Display/Alter screen.
You can key in the Adjust Value alone or with an
addre,ss. No address entered defaults to zero. The data
appears in the normal area as though it were at the
selected address, but the data is actually that data located
at the adjusted address, even though the address under
label ADRS is that from the address on the SELECTION
line. You can key a new address or use the PAGE key,
and'you still get the data from the adjusted address. The
address plus the Adjusted Value might cause the screen
to have a, twos-complement negative number.

Eight bytes of SP storage can be saved by the Block function.
An example of how you can save SP storage data is
QOWxxxxxxxx?

Note: You can use the 1 op code to verify if data exists at
the address before altering that data. This feature is very
helpful while running a block. After the 1, enter any number
of digits for the data that should be at that address. You
can alter any number of digits by also using an alter op code,
such as (=j. If the dats at that address does not match, no
alter occurs. If you have no match, and the data you are
matching and the data which you wish to alter match each
other, no alter occurs, nor does an error occur.
An example of how this command is used is:

The Insert/Extract Facilities screen (OV) lists facilities on the
left portion of the screen.

* INSERT/EXTRACT*

The insert/ extract function is a form of the display / alter
function, except that it uses scan rings. Therefore,
insert/ extract is slower than display / alter. The insert/extract
function is used in CE mode only.
Each screen can have up to six functions:
Display
Alter
Fast-Alter
Paging
Save from a Block
Alter from a Block
For many screens, entering the Fast-Alter command with
nothing after the op code (for example, OVI22=) causes the
data at the specified address to be shown on the SELECTION
line after the op code. This is useful as a check when
performing fast-alter using screens without full-screen alter.

SELECTION:

The clock can be stopped after invoking the QV facilities
screen, but must be stopped prior to invoking any facility
screen other than QVS or QVW.

==>

CLOCK STOP

The insert/extract function must be executed when the PU
is in the hardstop state with the exception of the Status Scan
Ring (OVS) screen and the W-command (OVW). These can
be executed in any state. Use the Operation Rate screen
functions (OOM or OOC) to hardstop the PU, or if necessary
use the W-command (20 or 2E). The CLOCK STOP
message is displayed in the system status area to indicate
this state.
To return the processor back to its normal state:
If OOM or OOC was used, enter OON next to SELECTION
and press ENTER. This resets any previously selected state
and the processor remains in the hardstop state. Pressing
the START key resumes normal operation.
If W2D or W2E was used, enter W2F next to SELECTION
and press ENTER. This resets any previously selected state
and the processor remains in the hardstop state. Entering
W30 and pressing ENTER resumes normal operation. Be
careful when using the W-command. Although it can be
issued in any state. the PU may have to be set to a particular
state for this command to function properly.

The screen can be displayed regardless of parity errors.
The facilities are always parity corrected, when any of them is
altered (updated), except in hardware fault conditions. Bad
parity fields are intensified on the screen.
The Insert/Extract screens can also be displayed by
selecting a % (for example 0% Bxx instead of oVBxx). This
eliminates all clock status checking. Any insert/extract
selection can then be made regardless of the state of the
three clocks in the processing unit.
Note: This feature should be used only if the state of the
clocks is known. The scanning process alters a ring if the
clocks are running.

The START key is disabled during the insert/extract
function, except after the ENTER key has been pressed. If
the scan data has been altered and the START key is pressed
instead of ENTER, the alter is voided, and the screen data is
red is played along with an error message. However, the alter
occurs if the fast-alter function is performed.

This digit is the subscript or offset of the byte postion within
the element. Byte subscripts are in hexadecimal and with a
zero origin. These numbers appear on the top of the screen

To display an Array screen that has more than one page, an
address is required on the SELECTION line. This address
consists of the minimum number of most significant (left side)
digits of an element address sufficient to define a page of the
array.
A specific element address can be specified. The address
is truncated to the minimum information needed to display a
page of the array. The displayed page contains the specific
element address specified.
Notes:
•

To perform a Screen Alter (for example, to place data in
the input fields), you must always leave the address on
the SELECTION line. If the address is erased or
changed, the alter is not successful.

•

To perform a Fast-Alter (i.e. address and data on the
SELECTION line), the full element address must be specified.

Control Store (QVAC) Warning

Warning: If you have a screen filled with FFs or most of
the Screen filled with FFs. use the following steps to
avoid entering invalid data into the control store array.
1. Key OOC or OOM next to SELECTION to stop the PU
ciock.
2. Press ENTER.
3. Press the START key several times.
4. Press ENTER. The screen should be redisplayed correctly.
Notes:
•

If you have doubts about the validity of your control
store data after you display. re-IML the processor.

•

When the PU is forcing a trapword. control storage
cannot be displayed because all positions may show up
as Fs. The write operation still works; so be careful not
to cause an alter that writes the Fs back into the array.
By microword-stepping one or more times and
redisplaying by pressing the ENTER key again. the
screen can be corrected. However. this condition does
not occur if the machine is first softstopped and then
hardstopped by going into microword-step operation rate
(OOM). Note that Control Store screen is not affected by
microword-stepping. but the other arrays and facilities
may be.

Save External Registers
The data from the External Registers screen can be saved by
the Block function. The format is OVXcxx? where c is a
channel number and xx is a field number. Only one field can
be saved per selection.

•

Spaces between characters are deleted before the
command is analyzed.

•

If more data is keyed than the selected field permits, the
message INV AL/D INPUT appears, and the cursor moves
to the right of the op code.

•

The op code MOVEs the data to, ANDs with, or ORs
with the data in the selected location(s}.
The facilities (field number) are numbered left to right,
top to bottom on the screen.

•

A period (.) is a digit place holder in the hex data.

The time-of-day clock is invalidated when
displaying/altering SR 42.

The scan rings can be placed into a loop and an 8-bit data
pattern can be scanned into the looped scan ring.
The following commands can be used to invoke this
function:
OVRLxx
OVRLxxO
OVRLxx=yy
where xx represents the scan ring number and yy represents
the optional bit patern in hex.
If the bit pattern is not specified, it defaults to X'OO'.
Looping continues until the MODE key is pressed.

This screen can be paged.

Note: An initial test pattern of X 'A5' and parity precedes
the data pattern. The eight-bit data pattern is scanned into
the specified scan ring without parity.

INSERT/EXTRACT W COMMAND (QVW) (GRP

2)

Note: This function is to be used only under the guidance of
your support structure.
The W-command sends a command across the Service Bus
Adapter (SBA) as a preliminary step to other manual
functions. The command is analyzed for valid hex values, and
an error message is displayed if incorrect. The scan ring
numbers are considered invalid. This command does not
require stopping of the PU clo~k to be invoked.

Warning: The W-command is a specialized function
designed for debuging activity of the hardware. The PU
must be set to the required state for the command to
function properly; otherwise. unreliable results occur.

(

Observe that SBA CMD xx SENT is displayed next to the
message indicator, where xx is the two-digit command
number. This message remains until another command
is sent or until a null (ENTER key only) is performed.
•

When the first manual op command is invoked, the
entire command appears along the SELECT/ON line. If
followed by a second command, only the selection
character (two-digit number) appears.
The W-command can be placed into a loop by using the
command QVWLxxyyyy, where L is the loop command,
xx represents the command to be performed and yyyy
equals the number of times it is to be performed. When
this command is used, the message SBA CMD SENT
YYYY is displayed next to the message indicator.

Block Execution Commands

MSG <.text>

SAVING DATA

Block execution commands are those commands that are
within a block.

This command allows you to enter informational messages
within a block. When the MSG command is encountered
during execution of the block, the text of the message is
displayed on line 23 of the display console. To make the
message easy to read, place a period (.) between each word
(recall that the code removes all blanks within a line).

aD ... ?

FAST-SELECTING A SCREEN (a screenid)
This is the most common type of block command. It is what
you would enter on the SELECTION line to get from one
screen to another in order to perform a function on the called
screen. Use the Q screenid command to either:
•

Alter some state of the machine (For an example, see line
03 on the "Editing a Block" screen).
Return information to the block facility (places the returned
information into the block save area via the ODS
command). (For an example, see lines OB and OC on the
"Editing a Block" screen.)

Note: The machine must be soft-stopped before executing a
QD command that modifies PU data.

DO.xx.blockname
This command is the first command in the block and appears
only once. xx is the loop number in hex. Replace it with the
number of times you want the block to execute. The name
of the block blockname is automatically inserted in the DO
command; therefore, do not try to change its name.

NOPS<.comment>
This command is used only for spacing or commenting
purposes.

* comment
This command is used only for spacing or commenting
purposes.

TOD<.comment>
Use this command to set the time-of-day clock in the save
area.

END.xxxx<.name.date>
This command must be the last command in a block; it
terminates the block. xxxx is a four-digit hex number
(entered by you when you first key in the END command) that
is compared with the CRC value when the block is saved.
You can enter name.date either when you first key in the
END command or when it is requested by the S (save)
command. (CRC value is sometimes called CHECKSUM.)

HALT <.comment>
Use the HALT command to immediately terminate execution
of the block even if more loops remain to be executed.
Note: Do not confuse this HALT command with the block
screen H (or OBH) command which suspends the execution
of a block at MATCH-WAIT only.

GOTO.line <.comment>
Use the GOTO command to go to the line number specified
and then continue processing there.

SETTING (AND SAVING) VARIABLE DATA
Sn= a screenid
Sn=aaa <.comment>
Use this command to set and save variable data within a
four-byte save area. You can enter up to five of these
commands within a block (substitute the number 1 to 5 for
the n in the command).
You have the following two ways of specifying this
command:
Sn= 0 screenid
Use the following two examples as an aid in
understanding this method.
S2=ODM000078? - This example indicates that the bytes
stored at locations 78 through 7B of main storage are to
be set into a save area named S2 (the save area can hold
up to four bytes of information).
S3=20DMOOOO78? - In this example, the number 2
immediately after the equal (=) sign indicates that the first
two bytes in main storage address 78 (that is, bytes 78
and 79) are to be skipped. Therefore, the save area
named S3 contains the bytes stored at storage locations
7A through 70. This method allows you to get to the
data you want to save in those instances where the field
contains more than four bytes. For example when you
specify a main storage address (as in this example). eight
bytes are available to you, but you can save only four of
the available eight bytes. [The number immediately
following the equal (=) sign indicates the number of bytes
to be skipped, proceeding from left to right. If the saved
data is less than four bytes long, the save area is padded
with zeroes to the right of the data.]
Sn=aaa <.comment>
Use this method if you either want to set a constant (for
example, S2=00000002) or you want to calculate and save
a variable by using an arithmetic expression (for example,
S3=S 1+00000008). In the above command, substitute the
number 1 through 5 for n, substitute Sl through S5 or an
eight-digit constant for aaa, and substitute one of the
following op codes for opcode.

TRANSFERRING CONTROL FROM ONE BLOCK TO
ANOTHER

av... ?

XFER.blockname

Use these commands to save data within the save area. For
a list of the 00 and OV commands that you can use to save
data, see "Display/Alter Block Save Area (ODS)" in Volume
18, Console functions. The question mark (?) after the
command instructs the processor to save the data pointed to
by the command. For example, the ODGE? command copies
the data in general register E, into a block save area. (You
can see what has been saved in the block save area by using
the Display / Alter ODS screen.)

Block Save Area The
that you point to via the
more information on the
Block Save Area (ODS)"

(

(

block save area is used to store data
00, OV, or Sn commands. For
block save area, see "Display / Alter
in Volume 18, Console Functions.

COMPARING DATA
COMP.aaa.bbb.line1 line2 line3 <.comment>
Use this command to compare aaa with bbb and as a result
of the comparison (see below). branch to line1, Iine2, or
line3. Substitute Sl through S5 or an eight-digit constant
for aaa and bbb. Line1, line2, and line3 are two-digit line
numbers (hex) that identify a line within the block.
If aaa < bbb then go to line1
If aaa = bbb then go to line2
If aaa > bbb then go to line3.
Example:·
COMP.S2.ooo00002.0A 11OB.CHECK.S2
In this example the data in area S2 is compared with constant
00000002. Execution continues at line OA if 52 is zero or
one, at line 11 if S2 is two, and at line OB if S2 is greater
than two. CHECK.S2 is an optional comment

. Use the XFER command to transfer control from the current
block to the block indicated by blockname. XFER terminates
the current block without error, regardless of how many loops
remain to be executed (has the same effect as the block
execution HALT command). The new block is activated and
starts running as t~ ough it were started from the SELECTION
line. The data saved by the save-variable, 00, or OV
commands (in the block save area) is not cleared when the
new block starts running; this data is saved from one block to
another.

WAITING FOR AN ADDRESS MATCH TO OCCUR
MATCH <.comment>
Use the MATCH command to Signal the block to stop running
and to begin waiting for the address compare set up by the
QAoo. command to occur. The MATCH command does not
need to follow the QAOo. command immediately. Also, once
you set up an address compare in a block, you do not need
to set up another match using the same conditions. The
following example illustrates a possible block:
QAHC8600
KEY.START.Ol
MATCH
OOM
KEY.START.02
OVAL108?
QAN
OON
KEY.START.02

Set compare for hard-stop on storage
address match
Start PU running
Wait for match to occur
Set op rate for microword step
Run two microwords
Record data in local storage
Set address compare to normal
Set op rate to normal
Start PU running again

NOTE: A QD or QV command cannot be executed between
the QA and MATCH commands.

SIMULATING THE START OR STOP KEY
KEY.START.xx<.comment>
KEY.STOP< .comment>
This command simulates pressing the START or STOP key on
the console. If you specify START, you must also provide a
two-digit hex number to indicate the number of times the key
is to be activated. You can also provide an optional
comment.

Executing a Block
You initiate the execution of a block with the A (activate)
command. The block starts to execute after the block data
and initial status information are displayed and the message
area is cleared.
The order of execution of the block commands depends on
those commands that change the flow of control (for
example, by using the compare command you can skip to a
predetermined line).

Using the Address Compare (QA... ) and MATCH
Commands
The only way you can suspend execution of a block is with
the Fast-Select Address Compare (OA ... ) command combined
with the block MATCH command. After the address compare
is set by the OA... command, the block executes until it
encounters a MATCH command. The block facility then
releases control and unlocks the keyboard so that normal
processing can begin (the block is transparent to the user).
When a match occurs, execution of the block resumes at
the next command following the MATCH command. Because
the match can occur anytime, the machine can be in any state
upon return to the block facility. If block execution resumes
when a keyboard is in manual mode, that keyboard is locked
until the block releases control. (During this time, the screen
that was displayed remains unchanged.)

Aborting a Block
If a block is executing, you can stop its execution by pressing
the MODE SEL key (if inhibited, the keyboard must be reset
first). Any Fast-Select commands waiting to be executed,
finish execution before termination occurs.
If a block is waiting for a match to occur, the block screen
Halt (H) command must be used. This terminates block
execution but leaves the address compare active (you can
clear this compare with the address compare screen OAN
command).

IML Effect on a Running Block
If you IML the machine while a block is waiting for a match
to occur, the block is halted.
If you want to trap or record an error condition, the block
you use must be active (waiting for a match) ~\Ihenever the
processor is running. Make the block active ty using the
block screen M command. See" Automatically Running a
Block at IML (M)."

microcode. erase the patch from the diskette. and remove the
patch name from the patch index Ireplace patchname with the
name of the patch you want to erase).

Enter K patchname (or asK patchname) on the SELECTION

transfer is not made. After you successfully transfer the
patch. it is automatically activ,eted.

ACTIVATING PATCHES (A patchname)

The action that occurs after entering K patchname is as
follOws:

Enter A patchname (or aBA patchname) on the SELECTION
line to apply the specified patch to the microco~e (replace
parchname with the name of the patch you want to activate).
The patch runs until an error occurs or the patch successfully
terminates.

The patch index is searched for patchname to locate the
patch. Then the patch is read into storage.

• ' Patchname is now compared with the patch names ori' the
new (to be copied to) diskette. If a patch with the same
name exists on the new (to be copied to) disitette, and it
;s in the active state. the transfer is not made. If the
same patch name is found and it is not active. the old
patch data is overwritten with the new patch data. If it is
not found. the new patch name is entered into the patch
list. and the patch is written in the first available ares on
the diskette.

DEACTIVATING PATCHES (D patchname)
Enter D patchname ,(or OsD patchname! on the SELECTION
line to remove the effects of the patch from the microcode

REMOTE SUPPORT FACILITY
The Remote Support Facility (RSF) enables linking the
display console, through a switched network, to a support
center or to a data bank system (if available) for diagnostic
assistance. The RSF is for service usage, and is not meant
to be used as a teleprocessing port.
If the maintenance package does not successfully resolve
a problem, the on-site service personnel can invoke a data
bank operation (if a data bank system is available) for
additional diagnostic information. The RSF also enables a
remote specialist to assist on-site service personnel in
problem resolution by observing and initiating functional
operations of the 4341. The RSF permits remote operation
of all system functions except those requiring manual
intervention (power on/off, IML, initial I/O control, etc.).

*GENERAL SELECTION*

Data Bank Invoke Procedures
Y
To establish a data bank connection:
J

1. Ensure that the 4341 has the required hardware (two
cards) installed. Information on the types of cards,
installation procedures, and card setup is in the
Installation Procedures.
Note: If you install the cards, run the diagnostics (MSS
option diagnostics, selection DO) before proceeding.
Also ensure that a COT 1DOOA coupler (or equivalent)
and dataphone are available.

2. Set the CE MODE switch ON, and stop the PU (QOM).
