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.

[Corion]: ambrus: I did that in 2012 and 2013, to try it out, and I found the available time to be worth more to me than the money
[Corion]: I've started that again this month (now forever instead of a limited time), and it already destresses me a lot
[holli]: There are Anti Vaxxer weeks at IKEA.
[Corion]: Of course, it's a 20% cut in the money I receive, while the work doesn't necessarily reduce at all, but my approach is to make the work take longer instead of fitting 5 days worth of work into 4
[holli]: 50% off all children coffins.
[Corion]: holli: Ooof :)
[hippo]: Cut should beless than 20% after tax, though. :-)
[Corion]: hippo: Yeah, but at least two years ago, it still was close enough to 20% cut
[Corion]: But I have a very positive experience with a four day workweek and a three day weekend. I can't easily go back though to full money.
[Corion]: That is easy without having to pay for a house, a wife or children though. If I had any of these, or any two of these, the decision wouldn't be that easy.
