Easier to see what you're trying to do.  If you accidentally put a space
between the two, it becomes space concatenation (breaking the filename),
rather than abuttal.  If you stick with the concatenation operator, you'll
notice when a space is where it doesn't belong.  I *always* use them, even
to put a space in the string (string||' '||restofstring).  As a result,
I've never had a problem with problems due to undesirable concatenation
side-effects.  I have seen a few people posting here (and comp.lang.rexx)
who do run into those problems using space concatenation.
