in reply to Passing a hash into a subroutine


Suggest you pass a reference to a hash and iterate over the keys to extract the value.
&callsub(\%hash); sub callsub { my($ref)=@_; foreach my $key(keys %$ref){ print $ref->{$key}; } }

Also suggest you get a copy of the "Perl cookbook" .Very handy for such day to day problems
HTH.
