Initializing a hash using a foreach loopby Paulster2 (Priest) |

Paulster2 has asked for the wisdom of the Perl Monks concerning the following question: I want to be able to dynamically update my hash. I am currently using the following to initialize it: The first two lines of the code goes out and extracts data from a config file, that being server names and IP addresses. With the code shown I have to update it if the number of entries changes in the configuration file. I want to replace it with something like this: But only get one entry where there should be five. The $num = $#Ip; seems to work just fine, at least it gives me the number back that I am expecting, so I take it that there is something wrong with my foreach loop. I am by no means an expert at hashes (yes, I know, some consider it the life blood of perl!!). I was wondering if someone had a better mouse trap for me. Many thanks in advance. Paulster2 You're so sly, but so am I. - Quote from the movie Manhunter. UPDATE: Thanks for the typo correction, Joost, I have to retype stuff over from another system. That part of the code is typed correctly on that system. I just fat fingered it here. Also, as I stated previously, I have inherited this code from another perl monger who did not use strict. With a couple thousand lines of code, it would make it a little difficult to implement strict now. I try to almost strictly use strict (pun intended). Maybe I will take the time to go back and do that, it may be worth the time, even if for only a learning experience! Thanks again to all for your responses!
