Why not just use Getopt::Long? Sample: 

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

my $abc = 1;
my $bar=1;
my $fii=1;
my $wee=1;

my $result = GetOptions("abc=i" => \$abc,
                        "bar=i" => \$bar,
                        "fii=i" => \$fii,
                        "wee=i" => \$wee
             );

| etc...

If I remember correctly (can't remember what I had for breakfast and I have the same thing every day) Getopt::Long is part of CORE and therefore you need to load it on your system.
