This is fine and dandy except that you have now LOST your positional parameters
(and if you are in a script - you may still need them). Furthermore - saving
your parameters first by doing something like:

	save_args="$*"

Is no help because now you will need to exercise some even fancier footwork to
get the parameters back the way they were if any contained IFS characters.

Like I said before - if you have the Korn shell, this is all *very* simple
if you create an array using "set -A" (or "set +A") and iterate your for-loop
based on "$array[@}" (the quotes are needed here). If you are using the
Bourne shell AND no longer need your postional parameters, then the method
described above will suit you just fine - If you still need the positional
positonal parameters (with sh) though - you'd better find another way (two
have been posted already).
