Studio:How do I extract the drive letter and use it to define the location of the Perl module?

The following code will extract the drive letter and use it to define the location of the Perl module:

use strict;
use File::Spec;
use vars qw($modulePath);
BEGIN
{
 my($vol, undef, undef) =
 File::Spec->splitpath($main::ascript->Database->Path);
 $modulePath = File::Spec->catpath($vol, File::Spec->catdir(,'Stride','lib', 'perl', 'S2S'));
}
use lib qq($modulePath);
use TestUtils;

A BEGIN block is evaluated as soon as it is encountered, so the $modulePath value will have a value by the time the 'use lib' statement is encountered.

If libraries are always installed on the system drive, $ENV{'SystemDrive'} can be used to determine the volume. Alternately, a registry setting or environment variable can be used.
