Why would it change?  You're checking the actual message data, not the
text of the message itself, right?   IIRC, the constraint name is in &16
(the 16th field in the message data) you're checking that field, not
scanning the second-level text, right?

I don't see why that position would ever change.  If it did change, it
would break a lot of programs.

I thought it was standard procedure for IBM to add additional fields to
the message data if they wanted to change the layout of the returned
data, rather than changing existing fields, so that existing programs
wouldn't break?

Or did I imagine that?
