You might be desiring what Perl calls packages and modules.

Start by creating a file called Mysubs.pm. In this file, put the following: 


package Mysubs;

use strict;
use warnings;

use base qw( Exporter );
our @EXPORT = qw( fee fi fo fum );

sub fee {
    print "You called Mysubs::fee()\n";
}

sub fi {
    print "You called Mysubs::fi()\n";
}

sub fo {
    print "You called Mysubs::fo()\n";
}

sub fum {
    print "You called Mysubs::fum()\n";
}

1;

Save that file in your script's working directory for simplicity for now. ...later you'll want to do something else with it and modify @INC to deal with that, but for now just save it in the same path as the main script.

Next create another script as follows: 

#!/usr/bin/perl

use strict;
use warnings;
use Mysubs;

fee();
fi();
fo();
fum();

[download]

Presto, it works. There are much more elegant constructs you can use as you get more familiar with modules and packages; exporting only those subs you need, object oriented design, and so on. But this should get you started. Our Tutorials section has a lot of good information to keep you busy for awhile. And merlyn's Aplaca book, "Learning Perl Objects, References & Modules", published by O'Reilly & Assoc. is a first class introduction and detailed course in Perl's modules and object oriented world.
