I'm not exactly sure of the term to use in asking this question, I guess "making a variable global" although that's not exactly what I'm trying to do. "Declare variable in parent" maybe?

Basically I put my common subs into a file and require it into all my scripts that need them (like probably everyone else). I am trying to define a global variable in my subs file that acts like it was defined in the main script file.

For some reason when I use syscall, if the variable(s) passed to it aren't declared in my main script, everything crashes.

So basically I need...

script.pl:

#!/usr/bin/perl
require "subs.lib";
[download]

subs.lib:

$blah = "something";
[download]

to behave like...

#!/usr/bin/perl
$blah = "something";
[download]

Hopefully I explained that good enough.
Thanks.
