Just to be nitpicky, %TRIM doesn't require the compiler to allocate
internal temporary variables.  It just sets a pointer the the proper
data and sets an internal length.  But you're right, %TRIM is not a
terribly speedy operation, and you're better off to find
alternatives.  In particular, whenever you see lots of %TRIM's in a
program, you should probably consider using VARYING length character
variables.
