Okay, now i apologize for being stupid whilst jumping a gun. By return
I meant that "return" called alone simply gives you a zero. But this
clearly misses a point of clearer educational value, vis. what we all
already believe:
return "anything";
is exactly that. However, vijay's question implies this method isn't
working for him, and the (unexplained) problems with multiple nested
subroutines might be resolved by just using global ("myless") variables
defined within the functions.
Of course, once that works, the script might be further resolved back
into the "$x=function()" style. I seem to believe i have had that
experience myself. Maybe...soon...
