Competitive Advantages of cp-6 APL
I.
A rich set of functions exceeding those, of many competitive products.
A. File I/O, blind I/O
.
1)
The full CP-6 file system facilities are available to the APL user.
This includes shared update as well as enqueue/dequeue to control access
in the shared mode.
2) Both translated, and untranslated{blind) I/O is provided.
B. Several unique commands are provided
1)
)SEALallows the installation to provide proprietary APL functions
for execution only. Also, individual functions in a workspace may be
locked to likewise prevent inspection of the algorithm.
2) )OBSERVE provides the ability to inspect the evaluations undertaken
for ~xecution of any line in the minutest detail.
3) )CATCH allows the user to intercept all assignments to a particular
variable to facilitate debugging.
C. System commands may be executed via the unary epsilon operator.
D. Sidetracking of errors and breaks is provided.
E. The system programmer functions
1)
Canonical representation to change function definition to and from text.
2) Workspace management to investigate attributes of workspace constituents.
3) Text editing to provide text index, search and replacement and comparison.
II.
An environment which admits expansion easily.
A. Both batch and on-line operations are accomodated.
B. A very flexible terminal interface mechanism admits considerable variety.
1)
Files are included.
2) Terminals without APL characters are accomodated.
C. The PL6 software factory has several beneficial aspects.
1)
Listings can contain much more documentary content.
2)
The language promotes the use of "structured" constructs.
D. The modularization of the CP-6 APL product will separate data, procedure
and monitor interface.
E. The commentary in the source for the processor will contain all the
information to produce the technical and data base manuals via an automated
process.

III.
Relatively efficient operations on large data aggregates.
A. Code is "compiled" for inner loops.
B. Use is made of the common library at all radix translation and elementary
function evaluation times.
C. Codestring is used to facilitate execution.
IV.
Workspace capacity is significantly greater than that of the competition.
A. A large virtual memory is provided with little operating system preemption.
B. Multiple segment dynamic memory will be utilized.
C. Typically CP-6 APL will provide 256K bytes vs, 32K bytes.
D. CP-6 APL will provide overflow symbol table processing beyond the "hashed"
symbol table capacity.

Differences between CP-V APL & CP-6 APL
It should be empasized that the CP-V AP~ design is, to a large extent, being
copied over into the APL processor for CP-6. CP~V APL is a field-proven, highly
competitive product. However, there are differences which should be exposed during
review.
I.
Differences caused by change of hardware
A. Word and byte size, but fortunately 36>32 and 9>8.
B. Floating point range is reduced which may require scal~ng of some processes.
C. The instruction set and the CPU organization are quite different.
1) The compiled code for interpretation of operators is new.
2) The use of PL6 minimizes much of this effect,
D. Trap~ are different.
II.
Differences caused by change of primary implementation vehicle.
A. The "structured" and documentary effects have been reviewed earlier.
B. PL6 generated code will be far from that which would be generated to
provide minimum procedure residency as was the intent in the CP-V product.
C. The abilty to produce technical documentation in an automated manner was
mentioned earlier.
D. As an empasis note, all of the above noted differences tend to promote
maintainability.
III.
Differences caused by change of operating system.
A. Some additional effects of hardware change are reflected in the operating
system interface.
1) Exceptional conditions vary.
2) NSA hardware is different from the Sigma map.
3) File granule size is different.
O. Many of the facilities of CP-6 expand upon those which had been in CP-V.
1) File open
2) File attributes
3)
"Privilege"
C. Dynamic memory management is particularly different.

Differences between CP-V APL & CP-6 APL - Contd.
IV.
New features have been added to Cp-6 APL.
A. Distinguished names
1) Had been available as I-BEAM and T-BAR functions.
2) Must be made capable of localization.
B. Shared variables are a new CP-6 APL facility which will be provided by
utilizing field-proven CP-V facilities.
1) Shared update files
2) Enqueue and dequeue
V. Delayed features - Two features of the GP-V APL processor have been eliminated
from the initial release of the CP-6 product.
A. Graphics functions
A. The interface to the data base manager, IDS-II.

Internally Perceived Risks
I.
The implementation vehicle, PL6
A.- Effects on processor and workspace size.
B. Effects on speed of various processes.
II. Personnel - It is an exceptional circumstance which could cause this to be
surfaced as a risk, but the health of the only team member from the original CP-V
team is of concern.
III.
Checkout
A. The novelty of CP6 is bound to cause problems. not the least of which is
concern about timely availability.
B. The purrent schedule does not admit sufficient time between earliest
assumed availabilty of checkout hardware/software and delivery time to accomodate
even the most optimistic checkout schedule.
