The problem currently is like this, there is lot of different functions that wants different data and along the way they call other functions and so on. and i really need a fast way to tell when even one of them fails without changing too much code. as im trying find a solution that does not make things even more complicated than they already are, but still doing it most effective and reasonable way possible.

So after many hours of pondering, i can't really think a better way of doing this than those lovely goto labels everyone loves so much.

Here is a demonstration of the current solution.

#!/usr/bin/perl

use strict;
use warnings;

my (%Numbers,$i);
my @Values = qw/first second third/;
$Numbers{$_} = ++$i for @Values;

for my $cur (@Values) {

        my $value  = &get_number  ($cur);
        $value    .= &get_ordinal ($cur);
        # more, more..

        print "$cur is $value\n";
        next;

        FAILED:
        print "WRONG: $cur, because: $@!\n";
        next;
}

sub get_number
{
  my $value = shift;
  if ($value eq "second") {
        &error("bad value");
  }
  return $Numbers{$value};
}

sub get_ordinal
{
  return substr(shift, -2);
}

sub error
{
  $@ = shift;
  goto FAILED;
}

Just thought to ask if anyone ever dash against this kind of problem and found more elegant solution than the following. And yes i would rewrite it if it was up to me.

-Tauno, Thank you for your time.
