[james28909]: it would be to much work just to get around renaming three subs lol
[james28909]: but you could put it all in one sub and return the same data type that was inputted. i could write a small example maybe
[Lady_Aleena]: Their uses are also vastly different.
[Lady_Aleena]: The first two make hashes and arrays from a file, the third returns data from a pre-existing hash.
[Lady_Aleena]: Well, HoH and AoH respectively.
