I'm glad you don't mind my belaboring this point. The tendency to do so
drives my friends (and wife) nuts.

Ah, but then it's making the assumption that the PR is correct. If I got the
wrong /COPY...

Oh well.  Have they left what little they had in there? Or do they now
assume that the compiler has taken care of it?

I've done both. Just for grins I modified one program that was used to
format ICD9 codes (medical diagnostic codes) and turned it into a function,
with call to one of those CEE API's to get one of the parameter lengths. I
also use a binding directory, but I have yet to do a service program.

You're right, I've been lucky. The problem you mention is similar to the
problem of submitting a call to a program with a string constant greater
than 32 characters, something I've noticed as a topic more than once.
