You are correct, you cannot shift the positional
parameters back onto the stack once they've been
shifted off.  I didn't realize that you wanted to
retain their position for use later on.  In that case,
I would take one of the other suggestions and simply:

#!/bin/sh
NUM=0
for i in $*; do
  let NUM=$NUM+1
  echo "$NUM: $i"
done

You might also be able to use the 'eval' builtin
command.

Brad.
