in reply to Check For null Arguments

A quick fix might be to use this:
if ($Do_Dir eq '') {

But, if you're interested in why your code doesn't work... Tip #6 from the Basic debugging checklist, B::Deparse

if ("$Do_Dir" == 'null') {

warnings also generates a message to let you know there is a problem.

    Thank You EVERYONE for taking the time to help me. Tweaking the "IF" statement to if (!$dir) did the trick :-) And YES, I'm reading/looking at "Basic debugging checklist" -Ray
