Mj1234 has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

I have a batch file as shown below. 
pushd %Root%
call perl Folder2\Perl1.pl

[download]

The batch file in turn calls the Perl1.pl file which contains the code as below 

use strict;
use warnings;

use lib "Folder3\\Folder4\\";
use Param;

my $Path = $Param::My_Path;
print "$Path\n";

[download]

When I execute the the batch file I get the error "Can't locate Param.pm in @INC (@INC contains: Folder3\Folder4\". But I want this path to be relative to the path %Root% pushd in my batch file.

Is there a way these paths can look from the %Root% for all the relative paths?

    Have you noticed the CAVEAT part in the documentation?

    use lib 'Folder3/Folder4';

    This works for me in Windows, Perl v5.16.2: BEGIN { push @INC, '.\subdir\\'; }

    The single period defines the current working directory and everything is relative from there.

    EDIT: Sorry, forgot the above shuold be wrapped in a BEGIN block
