One interpretation of the question is that you are looking for a way to save A particular key. Assuming this is what you want to do, here is some pseudo-code (untested). `my $SaveKey; while (my ($key, $val) = each %hash){ if (WHatever condition){ $SaveKey = $key; # Save this one } } my $SavedValue = $hash{$SaveKey}; # Use the saved key, if any` [download] Offense, like beauty, is in the eye of the beholder, and a fantasy. By guaranteeing freedom of expression, the First Amendment also guarntees offense.	[reply] [d/l]

save the key inside a variable? What do you mean? What are you actually trying to achieve?	[reply]

Is this what you want? `foreach my $variable (keys %hash){ my $value = $hash{$variable}; print "$variable\t$value\n"; }` [download]	[reply] [d/l]

"seems to mess things up". Perhaps you could give an example?	[reply]

To save the key, try: `my $value = $_;` [download] because $hash{$_} is the value of the array element, not the key. -- tbone1, YAPS (Yet Another Perl Schlub) And remember, if he succeeds, so what. - Chick McGee	[reply] [d/l]
