Dear Monks, I'm currently trying to add functionality to a program, my program is called mkpq and I'd like to add certain options such as mkpq -a <queuename>. I'm wondering if this is better off run as a custom subroutine or defined in @ARGV, here is what I have so far as in printing the command usage but I do not know how to reference the commands and store them for later use in the program.

$VERSION = 0.01;
$uname = "uname";
# Set ARGS
if (@ARGV < 1) {
    die "usage: $0 \n
                   -a <queuename> -- Add a queue\n
                   -r <queuename> -- Remove a queue\n
                   -s <queuename> -- Check queue/spooler status\n
                   -f <queuename> -- Force option\n
                   -h print this help file\n";
}

Any help at all would be greatly appreciated!

Update!

#!/usr/bin/perl -w
use strict;
use Getopt::Long;

my ($add,$remove,$status,$force);
my %add_opts;
GetOptions ( \%add_opts, 'queue=s', 'label=s' );

sub display_help {
        die "Usage:
                  -a <queuename> -- Add a queue\n
                  -r <queuename> -- Remove a queue\n
                  -s <queuename> -- Check queue/spooler status\n
                  -f <queuename> -- Force option\n
                  -v Version Information\n
                  -h print this help file\n";
}

GetOptions ( version => sub{ print "This is mkpq Version 0.01\n"; exit
+; } );
GetOptions ( help  => \&display_help );

if ($add_opts {'queue'}) {
        print "Test\n";
}
else {
        print &display_help;
}

First of all, thanks for all of the help everyone has provided. I do in fact have another question; since this program needs to be a bit intuitive. My initial thought process behind this program would be:

1.) The first switch will determine the course of the program. (mkpq -a or -r) I was going to have if statements for -a or -r, then sub-switches if you will.

Example mkpa -a -q <printername> (the a switch invokes the system commmand to add a printer -q will hold the string which is the name of the printer.

My question is this: How to I set this up in such a manner? Should I determine if () with subprocess' running under it?

if (a) {    # switch to add a queue
       do system($somecmd $q); #run system cmd with entered string.
