Home: Perl Programming Help: Intermediate: quick question on associative arrays

martialartsdrum Novice Nov 6, 2011, 8:48 AM Post #1 of 4 (1070 views) quick question on associative arrays Can't Post Hi, I originally put this in beginners, ~ 100 views with no response. Hopefully, I can get a response here. I really do need the assistance. I have ~ 10 associative arrays with data such as: %Vol_Name = Vol_ID, Vol_Name %Status = Vol_ID, Status %Date = Vol_ID, Date etc. What I would like to do, is loop through the Vol_Name array and flag all Vol_ID's of the other arrays. pseudo code: loop for size of Vol_Name { Get Vol_ID from Vol_Name array go through all the other arrays, searching for Vol_ID if found display data(). } How can I accomplish this? thanks John

Instead of 3 separate hashes, you should be using 1 HoH ( hash of hashes).

Noted that you originally posted in beginner. # get the keys for the Vol_Name array and loop through them foreach $volume (keys %Vol_Name) { # $volume will be set to each of the keys # get the value from the associative arrays printf ("The value in the Status array for %s is: %s\n", $volume, $Status{$volume}); printf ("The value in the Date array for %s is: %s\n", $volume, $Date{$volume}); # etc... }
