I have a subroutine that, amongst other things, chops a scalar variable, $dir, passed to it as an argument. The problem is that I need $dir intact (ie unchopped) after calling said subroutine, but it has been altered by the chop. I can't figure out how to pass the value (or more precisely, a copy of the value) of $dir to subroutine so that it's operations do not alter what $dir originally contained. I've read Mr. Wall's Camelbook and saw lots of info on hard, soft, and symbolic references, but nothing (that I could understand) about passing a copy of variable to a subroutine and not the variable itself.
