I would have missed this note if Barbara hadn't pointed it
out to me. Oh, there it is, it just arrived in my mailbox!

Hmmm, let me try to explain how the trim BIFs work.  %TRIM
performs two tasks:  1) sloughing leading blanks; and 2)
sloughing trailing blanks.  %TRIML and %TRIMR each perform
only one of these two tasks.  It is obvious to me that if
task 1 takes n units of time and task 2 takes m units of
time, doing both would require n+m units of time.

Now if you have some suggestion for a new algorithm that
would improve the performace of %TRIM, I would be quite
happy to consider it.

Cheers!  Hans
