NEMORANDUM FOR:
Charles R.
Troutman, Project Officer i
l FROM:
Stefan W. Frob' erg, Project Manager
SUBJECT:
USING AOS COBOL'FOR IFMIS INTERACTIVE PROGRAIO1ING i
REFERENCE:
NRC-10-81-359 (IFMIS -
Phase III)
This memo is in regard to our recent conversation when we' discussed the possibility of using COBOL as the primary language for IFMIS interactive programs rather than IDEA.
2[
In consulting with my staff and other AOS users the consensus definitely favored using COBOL rather than IDEA.
IFMIS was designed for IDEA and a few QUERY processes for all' of the on-line applications.
The design phase was undertaken before -an adequate base of experiesco had been developed for AOS COBOL.
The use of IDEA was a known factor, the interactive capabilities of COBOL were not.
Designing for IDEA was the correct approach under the circumstances.
The design is highly modular and can easily be converted.
As COBOL is more flexible and powerful some consoli-dr. tion of the existing modules would be desirable.
Both languages have their advantages and disadvantages.
COBOL is a government and industry standart. for. business systems.
It was designed to be transportable and is one of the most widely 4
supported languages.
It was also designed to be an English - like self-documenting language.
When properly structured it is easy to maintain.

. Mr. Charles R. Troutman Page 2 June 1, 1981 x-IDEA is unique to Data General computers.
It has a limited syntax and a built in processing structure.
Once learned it can be used to quickly implement interactive systems if they are kept modular.
It is especially fast for the less complex processes such as routine display functions.
It is not parti-cularly maintainable when applied to complex processes as various contortions are required to overcome its limited syntax and file handling capabilities.
There is of course, far fewer IDEn programmers than COBOL programmers.
COBOL programmers can easily be trained in t he screen handling aspects of COBOL faster than they can be taught an entirely new language.
Programmers without prior COBOL experience can be trained more quickly in IDEA because there are fewer things to learn.
COBOL is more " verbose" than IDEA but it has a far more powerful syntax and a greater range of file handling capabilities.
COBOL's biggest drawback is that it is simply not as fast as IDEA in developing the less complex screen operations.
IDEA is less " wordy" and has a built in processing structure.
For certain types of
,1 programs IDEA's disadvantages, limited syntax and file handling
,7, options, become its advantages.
It also has a powerful screen formatting utility (IFMT).
Data General has taken steps to overcome this problem with various fully interactive COBOL code generating facilities.
o SCORE - is currently installed on the ADPS Eclipse 350.
We have run some tests and find that it is roughly comparable in function to the screen formatting capabilities of IDEA.
The output of SCORE is generated COBOL statements which handle screen data manipulation and formatting.
These can then be copied into a COBOL program.
o MAJIC is available from Data General for approximately $3,500.
Some weeks ago V.
- Curry, C. Smyers and myself tested this package at Data General's Tyson Corner Facility.
It generates various types of fully operational COBOL programs as a result of an interactive session with a user.
I found it useful for the rar id development of simple processes which enter and display data.
It will not handle multi-file updates or computations on the input variables.
The output COBOL code however can easily be modified to accomplish more processing.

' Mr. Charles R. Troutman Page 3 June 1, 1981 is available at an approximate cost of $6,300.
o PROXY I have heard about-this package at a Data G2neral Users Group meeting.
It is supposed to have more capabilities than MAJIC and will generate more complex programs.
My conclusions are as follows:
- 1. COBOL should be used for all IFMIS programming and substituted for IDEA and QUERY where they are specified.
- 2. MAJIC and PROXY should be reviewed ac potential tools for the quick development of the systems less complex routine processes which can currently be more quickly developed by IDEA.
This would overcome the one IDEA advantage.
These packages should be reviewed with the perspective of how well can they do what they are designed to do not as complete replacements for all scratch COBOL programming.
The cost of these packages is completely nominal when compared to the cost of just a handful of scratch written COBOL programs.
/
3.
There would be no adverse impact on IFMIS contract costs with a
\\0 switch to COBOL and the acquisition by ADPS of a useful COBOL program code generator.
4.
If we can resolve this issue quickly, within a matter of days, the time delays in re-orienting the project will be minimal and there will be no major impact on the overall system due to the language change.
Please feel free to contact me should you have any questions or need additional information.
