IMHO the root cause is that people see what they expect to see; hence the value of code and design reviews, where the code is read by a fresh pair of eyes with no expectations. I've often found that when I ask someone else for help and start explaining what the code is supposed to do, my view shifts enough that I spot the error mid explanation. I suspect that this is universal.
Meanwhile, I need to add the abutted parenthesis to my Safe REXX paper ;-) -- Shmuel (Seymour J.)

A: Not where you think. Well, I finally figured out why the -3. And it is because LISTDSI as a function is not recognized as a command, hence -3 (which at least one of you was indicating). I wish to thank you all for your assistance and even code samples that are NOT what I'm working on. For clarity only, at this point I am using a DDname not a DSN, which is why it was followed by "FILE". Given how much REXX code I've been doing in CMS and TSO over the past 10 years, I think the root cause of this stems from a concussion. I've noticed other oddities since that concussion. But things are getting better. So the question of where LISTDSI is found is moot, in that my environment is correct once using "CC = 'LISTDSI' ('SYSUT1 FILE')". I now return you to other more interesting topics.
