I thought someone would have mentioned it by now, but... The trick I've used on occasion is to leave a value on the stack. The hard part is usually making sure it's in the right place on the stack and doesn't get wiped by other operators. This might be helped by using a mark and counttomark to figure out how far to roll the stack to deposit the value. Again, make sure it's not a composite object. An integer should be no problem.... -- John Kohl <jtkohl@ATHENA.MIT.EDU> or <jtkohl@MIT.EDU> Digital Equipment Corporation/Project Athena (The above opinions are MINE.
