Home: Perl Programming Help: Intermediate: Reference or not?

jolt Deleted Jul 30, 2000, 3:11 PM Post #1 of 2 (536 views) Reference or not? Can't Post I'm using perl to generate reports. Each line contains a hostname and size field I can view hostnames and how many times that host has requested something. However I'd like to add the total size amount of all the hosts' requests. How do I do this? I've tried to use the following with no success: #Count hosts (works) $hash{$host}++ #Count size per host (doesn't work) $hash{host}->{$size}++ /Thanks!
