Thanks to Jose and all others who posted. I now have a working nested hash and a better understanding of them.

Since you declared your 'time' beeing an hash as follow: %time=(); You should not be using the arrow notation. Use this intead : $time{key} If really want to arrow notation, you need to declare 'time' like this : my $time={};#reference to an anonymous hash #filling-in as follow $time->{$custname}{$custsub}{$site}{$YYMMDDay}{'start'} = $hhmmsss; #dereference stuff foreach my $c (sort keys %{$time} ) { bla bla .. } HTH, José. > foreach my $s (sort keys %{$time->{$c}->{$cs}}) { > print "Site $c.$cs.$s \n" > #..etc . next branch . etc > } > } > } > > > -----Original Message----- > From: NYIMI Jose (BMB) [mailto:[EMAIL PROTECTED]] > Sent: Monday, January 20, 2003 6:11 AM > To: [EMAIL PROTECTED]; Beginners Perl > Subject: RE: Nested hash creation help ! > > > Afterwards, to see how your nested hash looks like, > try this: > > use Data::Dumper; > print Dumper(\%time); > > José. > > > -----Original Message----- > > From: Scot Needy [mailto:[EMAIL PROTECTED]] > > Sent: Monday, January 20, 2003 6:50 AM > > To: Beginners Perl > > Subject: Nested hash creation help ! > > > > > > Hi; > > > > Trying to crate a nested hash from variables parsed out of > log files > > but as I am a "Beginner Perl' coder it is failing terribly.
