Re^4: Extracting non-consecutive but related items from an array.

And, why did we have to reference \ @apps_info? couldn't we use it without referencing?

No particular reason, it's just that that's the way I like doing things. This way, the information contained in one line in the input file stays readily identifiable (it's one element of the array for that server), whereas pushing on the first level array would result in a flat list. But it's just a preference thing, I guess.
