Hans,

Although this doesn't anser Don's question, I have seen this error 
caused by not passing *OMIT to the CEETSTA API.  I know this can 
type of error can be caused by simply not passing a parameter for 
any CEE API parameter that specifies that it is omissible.  To 
correct this error you must specify *OMIT, even if it is the last parameter 
passed.  Even the people who wrote the sample code for the RPG 
manuals incorporated this bug. Failure to pass *OMIT can cause 
memory to be corrupted in the most unlikely places (experience tells 
me x'0000' may pop up in user spaces or static program variables.)

Sure it explains it.  Some program in the application is
corrupting some area of storage.  By changing the affected
program (not the buggy program) to an RPG III program, the
corruption is happening in some storage which does not
manifest itself in the same way.  The problem is still
there, lurking quietly, waiting for the opportunity to pop
up again when some other condition changes.

As I stated before, we've seen several reports of
"mysterious MCH3601" problems and they've all turned out to
be bugs in the application, not in the ILE RPG compiler or
run-time.  I'm not trying to deflect criticism away from
RPG, but our experience tells us that the most likely
source of the problem is somewhere in the application.  I
know from my own experience, that this type of problem is
the hardest to debug.

Cheers!  Hans
