Whoa, Bob,

I won't even go into the 17 year old testosterone driven arena =:-0, but
IMHO, there is nothing "evil" about trapping "MCH0000" errors.  Or any
other errors.

It's not so much as "what" is trapped, as "how" it's trapped.  If an RPG
program pops up a "invalid array index" error. It's not a problem unless
one does not program in a graceful out.

I agree, only a twit would code MONMSG(CPF0000) RETURN as a first level
error trapping.  Ever since Q38 was published, there have been CL
programs to percolate the error up to the caller.  Maybe it's time to
make something old "new" again?
