I'm working on a little program that uses subs, but I'm having difficulty wrapping my brain around how to make local variables in subs and then pass the values contained in the subs out to main. The text book for this class (which I'm not wholly impressed with) says that, since all variables in Perl are global (unless otherwise specified) just call the variable from outside the sub.

But I don't want to do that, because then I have variables stepping all over each other and it's just a damned mess.

So, my questions are:

1) Is this were "my" comes in? What about "local?" What's the difference? I understand local went out with the goto statement. True?

2) How do I return a value from a sub to main, if Perl doesn't have a return statement?

If there's a tutorial I'm missing (I looked, but they all seem very advanced compared to what I'm doing) just point me to it and I'll go look

Thanks!
