in reply to printing the subscript separator

So what you want is to print out the subscript separator $;, but not print it out if it is completely blank (i.e. just whitespace, empty string), or if it is undefined?

If I understand you right you want:

if ( defined $operator and $operator =~ /\S/ ) { #print operator here #it is defined and contains something #that is not whitespace } else { #do something else as $operator is either #not defined or it does not contain a #non whitespace character }
If I misinterpretted your intention let us know.

    Thanks, I like the way you put things, but I figured out what was wrong and updated my OP.
