in reply to Passing file location in a subroutine

welcome Rapazzini.. but ???

First have a look at Markup in the Monastery to put code tags around your code.
After this, your code does not make much sense to me. what org::item::essential is? a subroutine of the org::item class? what that (unknown to me) sub does? Normally a file path form depend on the underlaying operating system: 
     my $linux_path = '/usr/bin/perl';

     my $win_path   = 'c:\scripts\my.log';

     my $old_macos  = 'Hard Drive:My Folder:My Document';  #dunno

You have to pay attention when you pass file names to subs to the current directory where the program works. if you run your program in the /some/path and you do not change current directory while running, then a bare_filename.ext will be relative to /some/path ending to be /some/path/bare_filename.ext

To deal with file path in a OS portable manner you can use the core module File::Spec as simply as: 
$path = File::Spec->catfile( @directories, $filename );

Re^2: Passing file location in a subroutine

    Thank you for the support. Let me clear the thing I have placed the .pm file code here.I now will try to explain it what I understood. I want to call it by using .pl where I will use the pic.pm file 
    package alter;

sub onPerform
{
  my $nec = shift;
  my $ipic1 = org::item::essential($nec, "Input Picture");
my $(ipic) = $nec->locateAbsolutepath($ipic1);

    "org::item::essential" is a module of to get some parameters and the "input picture" have to get the parameters that will be assigned to $ipic1. The $(ipic) will take the $ipic1. I want to call the subroutine "onPerform" to input the "Input Picture" 
    #!/usr/bin/perl -w
use pic;#.pm file

my $rapaz1 = 'C:/Users/RAPAZ/Desktop/try/train19_01.chm';


my $rapaz = alter->onPerform();
$rapaz-> {"Input Picture"} = ($rapaz1);

    Please help me how to call the subroutine and pass the file location "input picture" so that it gets the parameter and get prepared for $(ipic)
