thank you all. I was banging my head and I kept re-reading and it didn't make sense at the time.

:) Been there, done that, took a break to practice :)

When I'm stuck and a regular break doesn't help, an exercise break helps

I start a new directory and walk-through something like Simple Module Tutorial, typing it myself instead of copy/paste

Instead of commenting/uncommenting lines, I save each to a different file (MyScript3.pl...)

The benefits 1) it stick in my memory (like muscle memory) 2) I have short example (in my style) available for copy/review at anytime

Eventually I back this up in version control
