number of the device to be add~.
Can be specified as either 5 Qr a
decimal number from 0 to 255:
5 indicates that the device can be
switched (that is, physically
attached to two adjacent channels).
The designated channel is the
lower of the two channels.
o to 255 indicates the priority of
a device that cannot be switched,
with 0 indicating the highest
priority. If k is not given. the
assumed priority is 255.

SYSREC-cuu,SYSCAT- {cuUIUA} [,SYSDMP-cuu] I
The DEF command is used to assign SYSREC,
the logical device for the system recorder

device for the VSAM-E master catalog
SYSOMP, the logical device for the highspeed system dump.
SYSCAT=cuu Indicates the channel and

to be assigned to SYSCAT.
SYSREC=cuu Indicates the channel and
unit number of the physical device
to be assigned to SYSREC.
SYSOMP=cuu Indicates the channel and
unit number of the physical device
assigned to SYSDMP. SYSDMP
can be assigned to any CKD or
FBA device. The assignment cannot be changed until the next IPL.

The OPO command, which is mandatory,
is used to define the pape data set.
The operands of the OPO command may be
given in any order.
TYPE=N TYPE=N is the default and indicates that the page data set need
not be formatted.
If TYPE=N is specified but the
page data set does not exist or the
extent limits have been changed,
TYPE=N is ignored and the page
data set is formatted during IPL.
TYPE=F Indicates that the page data set is

part of the formatted extent has
been destroyed. The TYPE operand is ignored for FBA devices.

1) The bucket bytes handle undefined records. Bit 0 of byte 28 at open time determines
the mode set of a printer with UCS. If bit 0= I, the mode is set so that data checks
occur if on invalid character is printed. Otherwise, mode is set to suppress doto checks.
The use of the UCS parameter determines the setting of this bit. If STlIST=YES, byte
31 saves the STlIST control byte provided by the Pur macro.
2} The 2 byte bucket saves print overflow conditions if CTLCHR= ASA. If STLlST= YES,
byte 38 contoins the current $lLlST control byte. Byte 39 is set by the Pur macro to
indicate spacing or skipping. (X'OO' no spacing, no skipping; X'Ol' spacin9i
X'02' skipping).

* The format of the tape data file DTF is different starting at byte 44.
The location indicated by the numbers in the left hand column can contain only
one of the foctors listed under Contents.
The factor used for any given DTF table is determined by whether the file record
format is-fixed, variable or undefined, and by other DTF parameters as indicated.
A blank in the record column indicotes that the contents apply to all record types.

Record Format explanation
F :::: Fixed Record
V :::: Variable
U :::: Undefined
S :::: Spanned (variable format superset)
The deb lockers ore scratch areas used by the modules t~ sove data from one GET/
PUT macro instruction to another. In the text and listings, they ore referred to by
the names DEBlOCKERl to 6. These are not labels; they are comments used to
make it easier to follow the listings.

For 3504, 3505. 3525 input or output files using ERROPT, byte 3, bit 3 is set on if a
permanent error occurs. Byte2, bit 6 is set on to allow you to accept permanent errors_
Note 9:
If user error routine is specified and the user needs the sense information to further
process the error, byte 12,bit 2 mustalosbe set. Otherwise. the supervisor error routine
will clear off the status on return and the sense information ist not available.
Note 10: 3895 error codes are returned in CCB Byte 8. Refer to 3895 document reader/inscriber

A null entry is generated at supervisor generation time for each device to be supported
by the supervisor. Then standard physical unit assignments are made to the PUB table.
Physical unit assignments can also be made during IPL. PUBs are ordered by channel

any device of the installation.

subtask is ATTACHed after a STXIT AS macro has been issued by teh maintask,
the subtaks will receive the AS routine address specified by the maintask only if
the AITACH macro for that subtask has the ABSAVE parameter specified. The
subtask can override this by issuing its own STXIT AB macro.

TRANSLATION CONTROL AND COPY BLOCKS
Thefollowing control and copy blocks are used to copy and translale a
eea and channel program
for a virtual mode 1/0 request:
• A translation control block (CCWTCB, or abbreviated asTeS). This block is used as a work
and save area during translation.
• A eea
copy block. The user eea and sense CCW (if any) are copied into this block. The eea
copy block also contains information about the copied and translated channel program.
• CCW copy blocks. Each block contains copy locations for up to 7 contiguous CCWs and queueing information.
• IDAL blocks. Blocks used for building Indirect Data Address Lists for CCWs having IOALs or
for data areas which cross page boundaries.
• Fix information blocks. Each block contains a bit string for fix information for a block of
1088K of real storage. One or more fix informations blocks are generated if a page is fixed
at a location greater than 384K (information for page frames up to that address is kept in the
CCB copy block).
