i like this solution, however can i add to the hash reference being passed to each subroutine? i ask because my subroutines add to the information being handed down with each nesting:

#!/usr/bin/perl -w

use strict;

my $source = "tftp"; my $destination = "run";

&first;

sub first {
  my %argsHash = ( Source => $source,
                   Destination => $destination, );

  &second(\%argsHash);
}

sub second {
  my $args = shift;

  my $error = "problems!";

  print "This works, but i need to pass the error value
         to the third subroutine, in addition to
         $args->{Source} and $args->{Destination}\n";

  &third();
}

its here that i get confused. not only do i need to pass the existing value of $args to the third subroutine, but i also need to pass the value of $error as well. i've tried a little experimenting with &third(\$args); and although its passed, its passed as a scalar rather than a hash it seems. i see that i can add the value of $error within the second subroutine, such as:

$args->{Error} = $error;

but i'm stuck on how to pass this new hash to the next subroutine.

humbly -c
