That's why I like using code from other files.

Code reuse is a Good Thing. The way this is usually done in Perl is with modules.

TIMTOWTDI but one example using Exporter is shown here to get you started. Here is a module MyPaths.pm which I have just written:

use strict;
use warnings;

package MyPaths;

use parent 'Exporter';

our @EXPORT_OK = qw/$pathfoo $pathbar/;

our $pathfoo = '/path/foo';
our $pathbar = '/otherpath/bar';

1;

And here is importtest.pl which makes use of that module:

#!/usr/bin/env perl
use strict;
use warnings;

use lib '.';

use MyPaths '/path/';

print "paths are $pathfoo and $pathbar\n";

[download]

The use statement will import any exportable symbols from the module which match the regular expression. When we run importtest.pl we see this:

$ ./importtest.pl 
paths are /path/foo and /otherpath/bar
$

[download]

There is a lot more to modules and exporting/importing than this but it shows you how to get going with the basics.
