Light weight OO is a neat solution for this. Consider:

use strict;
use warnings;


my $obj = bless {};
my $verb = 'AddAccount';

for my $os (qw(SUN HP XP)) {
    my $sub = $obj->can ("${os}AddAccount");
    
    if (! $sub) {
        print "Don't know how to $verb for $os\n";
    } else {
        $sub->($obj);
    }
}


sub LINUXAddAccount {
    my ($self) = @_;
    
    print "Linux goes moo\n";
}


sub AIXAddAccount {
    my ($self) = @_;
    
    print "AIX goes moo\n";
}


sub HPAddAccount {
    my ($self) = @_;
    
    print "HP goes moo\n";
}


sub SUNAddAccount {
    my ($self) = @_;
    
    print "SUN goes moo\n";
}

Prints:

SUN goes moo
HP goes moo
Don't know how to AddAccount for XP

Note that all you need do to support XPAddAccount is add the sub - no tables to update or any other code changes required.
