Hi Juergen,

we worked with this compiler for ten years or more,
now we have EP PL/1 exclusively since 2002 or so.

Since the problem is in the preprocessor stage: did you change
some of your macros prior to that compilation? If so, can you fall back
to the old versions and try to compile that?

Are your programs large? The problem with the old compiler versions was
that they are limited in working storage size (maybe 24 bit restrictions),
so that programs with more than - say - 800 variable definitions don't compile. That's why we migrated very early to the newer versions, when they were available.
But that's a problem that should not show up in the preprocessor stage.

What about your other PL/1 programs (using the same macros)?
Do they compile successfully? Same size?

Have you considered contacting Peter Elderon? He is very helpful
on all problems concerning PL/1 ... but I don't know if he can help you
with these old compiler versions.

Or members of PL/1 GUIDE?

Kind regards

Bernd

Hi,

unfortunately a very old PL1 Compiler (5668-910 IBM OS PL/I OPTIMIZING COMPILER 
 V2.3) is still used on our systems (z/OS V1.13).

Now we get the following error message during compile runs:

ERROR ID L   LINE    MESSAGE DESCRIPTION
UNRECOVERABLE DIAGNOSTIC MESSAGES IEL0001I U 595 PREPROCESSOR ERROR NUMBER 0 DURING PHASE 'CA'.

The message explanation says, that this error is due to a fault in the 
preprocessor, not the source program.
It seems that this situation occurs after using a new maintenance level of 
z/OS, but of course the compiler itself didn't change.

I think it doesn't make sense to open a PMR with IBM, because the compiler is 
out of service since 12-31-2003!

So any help, where we should look for is apprechiated.

Regards.
Juergen
