RE: %Trim dilemma

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

That's debatable, particularly when dealing with a language, like RPG,
that doesn't provide full NULL support.

If you consider strings to be sets of characters, then you'd consider
that in set theory the NULL set and the EMPTY set are one and the same.

Interesting tidbit, Oracle treats EMPTY strings as NULL strings and vice
versa.

However, given that DB2 doesn't treat NULL strings as EMPTY strings, and
given that RPG doesn't support NULL variables, I probably should have
said empty instead of NULL <grin>
