Reply with quote

I'm looking at a problem in a VSE environment where they are adding code to a COBOL74 program and getting the following when trying to compile:

0S03I PROGRAM CHECK INTERRUPTION - HEX LOCATION 00505794 -
INTERRUPTION CODE 01 - OPERATION EXCEPTION

I can remove 1 line of code and then compile ok. Add the 1 line back in, and the above exception occurs. Another developer said he removed many lines of code from another part of the program, but still got the error.

Not sure where to start looking, is this a COBOL74 limitation, or compile options not set correctly?

Anyone point me in the right direction?

Thanks.

Hello,

How many lines of non-comment code are in the source?

When it does compile successfully, how big is the object module?

Does one particular line of code cause the abend or does adding any more code cause the problem?

What warnings are generated when the compile is successful?

It may help if you post the first few lines of output from the compiler.

Program has about 22000 lines of non-comment code. Object module is 1357848 bytes.

Does not seem to be related to a particular line of code.

There are a LOT of warning messages on successful compile. Let me know if you need to see them and I will attach in a text file.

Here is some of the ouput from compile:

Code:

Thanks. I don't think my problem is related to that though?

I'm adding more info from the dump. Could be a limitation of the operating environment?

Code:

Hello,

Well, 22000 lines is more than big. . .

As an experiment, you might take some large PERFORMed routine and make this a called module (thereby reducing the source by as many lines as possible by a simple change). As this would really be "part" of the large module, suggest it be called statically (these should probably be in sync and not dynamic).

I would also get rid of many/most (preferably all) of the warnings.

It is also possible that a WORKFILE has gone beyond the extent. Is this WORK01,,,1,500 used for all compiles?

What do you mean by "another part of the program."

Different COBOL Section?

This seems to be a very large load module.

A S0C1 indicates a bad OP CODE.

Maybe the load module is just too big?

Perhaps breaking this behemoth down into sub-programs, although I don't know if your version of VSE COBOL and the Operating System supports Dynamic Calls, because Static Calls will put you back in the same dilemma (one giant load module).

Do you have any other Production load modules of this size or greater?

Hello,

My guess that the case of the "too large" load module hasn't been reached - yet icon_smile.gif - because the compile abends rather than the link. . . Of course, the object might be larger than some limit. . .

Another guess is that some "work table" the compiler uses has gone out of bounds. . .

Yep, it's big. I tried increasing the workfile extents, same result. I think you're right, will just need to break the program down, it's just too big.

Sorry, should've been more clear. He apparently removed unused paragraphs of code (don't ask me why there is unused code, I have no idea) from the program. I don't know if it was commented or not.

I'd leave the warnings alone for now - they all have the usual assumptions (code in area A, assume B, etc.).

I'm thinking the same. It's not an issue with the program or load module size, but some kind of space issue with the compiler/operating system. Although the program is almost too big to be manageable, should be broken down anyway.

I'm going to ask this anyway, although I might get flamed. Are there any hard-coded (and very large) WS internal tables in this program, which contain Static data?

They can be changed to Static Assembler Tables and be made available to the program (Dynamically Loaded) via a small Assembler sub-program, which issues a CDLOAD Macro and returns the LP address and length back to the Caller in a parmarea of the target table.

Addressability will then be done via the LINKAGE SECTION and the storage will be external to the program.

Just a SWAG.... icon_wink.gif

Again, and only a guess, i believe there are too many "things" and the compiler has run amok (rather than "things" that are "too big"). . .

A compiler i worked once upon a time had a fatal problem when there were too many characters of data names (not the number of names, but the over length of these names). . . We fixed this by taking the array out of memory and using disk for the really large code. . .

As the source for that cobol74 compiler is probably not available, upping limits internally is not an option icon_wink.gif

Yep, there are programs here that have been added to and added to until they are monsters.

What are your thoughts on converting to COBOL85? I was doing some experimenting and created a COBOL85 program double the size of my problem program by duplicating code and compiled it with no issues. Any thoughts as to why that would be. Does the newer compiler use less memory? The load module is siginificantly smaller as well.

Thanks for all the input.

Almost always worthwhile upgrading to a version that is only 25 years old, as opposed to 36 years old.

But seriously - upgrade for sure, esp. since you can't change the current program.
