I don't want to start a huge debate here, but at first glance I think that
this code may not be the best solution in all circumstances, primarily
because of the duplicated call to %TRIM.  Unless the RPG optimizer is very
smart, this would cause the work required to trim the field to be done
twice.  This would include allocating two internal temporary variables and
copying the data to both variables.

I recognize that Rob wants to remove the work variable, and I guess the
issue that needs to be addressed is the logic for that requirement.  It may
be to remove the requirement for knowing the size of the work variable ahead
of time, but without knowing that, my initial reaction is that this code
performs unnecessary work and should be avoided.

My nickel, adjusted for inflation.
