If you nicely indent your code there should never be any need for such heavy comments...
I find such comments very useful. They help make code much more readable. Indentation is also good.
The &-form of sub call is obsolete and should never be used nowadays unless when one really know what he's doing.
Lies! There is no other way to call a sub. Stop trying to confuse the newbie.
Update: re-reading the code I realize that obviously the OP's problem may just be that he calls his sub out of the while loop, then he uses the return value of that sub, saved into a variable, every time it is needed inside the loop. OTOH there are IMHO bigger problems with his code, as signalled above.
Translation: The problem was too tough for you, so you resorted to attacking it for stylistic differeneces. Shame on you.
