I'm not clear what you want to do Jeff. Is it something like this?
my $cost;
sub increaseCost {
my $delta = shift;
$cost += $delta;
}
sub decreaseCost {
my $delta = shift;
increaseCost(-$delta);
}
In which case you should write it exactly this way and forget
about aliases. If I'm guessing wrongly then let us know.
Cheers,
Rob
