( #3333=superdoc: print w/replies, xml ) Need Help??

I didn't know about "our" (and still don't, but at least now I know what I should be looking for)
Nooo!!! You should not be looking at our! Lexical variables (my) are what you should be learning about first and they should be preferred to global variables (our) in almost all cases.

Given you are a Perl beginner, you need to master the basics of scoping and how to write subroutines. Start by defining all your subroutines at the top of the file and pass parameters to each subroutine. Do not succumb to the evil of having subroutines use global variables. Instead think about your code, what each subroutine does and what it needs, and pass parameters to each subroutine for use as local variables within the subroutine. For example:

use strict; use warnings; sub my_print { my $i = shift; print $i; } foreach my $j (0, 1) { my_print($j); }

Further reading from the Perl monks Tutorials section:

As for learning Perl, take a look at learn.perl.org and Perl Tutorial Hub. Also, be sure to refer to the Perl online documentation. Good luck!

    [Eily]: is the Bishop of hearts higher or lower ranked than the Jack?
    [ambrus]: Higher.
    [Eily]: Discipulus what's the merchandise? Other bi-people?
    [1nickt]: marto would like to hear that. Of course he speaks very deliberately and dramatically, allowing pauses between words, so if anybody could pull it off it would be him, or someone impersonating him ...
    [Eily]: Discipulus that's a chess joke BTW right? Because bishops don't walk straight :D
    [choroba]: stop making chessy jokes about bishops!
    [choroba]: I mean cheesy
    [LanX]: lol
    [ambrus]: no, the chess bishop itself is a joke on real bi-shops
    [ambrus]: or at least on the stereotype of bi-shops
