Hi,
Thanks for that, although it didn't work at least I think so.
foreach my $sorted ( sort { $HoH{$a}->{"uid"} <=> $HoH{$b}->{"uid"} } keys %HoH)
{
print STDOUT "$HoH{$sorted}\n"
}
and all I get out is:
perl sort.pl
HASH(0x89de3d0)
HASH(0x8a05d40)
HASH(0x8a05dd0)
HASH(0x8a05e60)

Any thoughts on this?
