in reply to Memory utilization and hashes

Your posted code will not run. You have an error in a variable name here: chomp $;. You have unbalanced [] here:%pairs{$l[1}{$l[2]} = $l[3];. And hash element references should start with $ not %.

In addition, you assign $_ to $l, use it as a scalar: @vals = split /;/, $l;, and then index it as an array:%pairs{$l[1]}{$l[2]} = $l[3];

Use strict; use warnings; Only post code that compiles.
