Use command usage - Newbie

When using the use command does it assume the other module is in the
same directory or path? What is the logical look-up ?

It looks in all directories that are in the @INC array. If you need to
add a new directory to that list, you need to add it to the @INC array
before using the module. Since 'use' happens at compile time, though,
you need to either modify @INC in a BEGIN block, or preferably use the
'lib' pragma:

#!/usr/bin/perl
use strict;
use warnings;
use lib 'some/other/directory/';
use MyNonStandardLocationModule;
