This is a situation that often occurs in debug when the dealing with

Strangely enough, SEP debug shows the contents just fine.

What I think is probably happening is that the dump is trying to show
all 32000 characters of cmd, but that it hits an offset error because
there isn't actually 32000 bytes worth of storage at the cmdPtr pointer.

Even more interesting! I made a tweak and set the lengths to the exact
size of the command I was testing and all of the variables show up in
the dump. I believe your hypothesis is correct.

It's sort of academic to me; I'm not going to raise a PMR over it. I
puzzled on it a while and can't see how to correct it. I can't really
change my code because I need to set aside the maximum amount of storage
possible for a command - 32000 bytes. Yet IBM i isn't necessarily going
to set that aside for me when it calls my program, so there's no real
way to reconcile the two; if the OS would return a VARCHAR we'd be all
set...

Thanks Barbara!
