in reply to Read from file to two arrays.
If parsing the CSV is an issue at all, you might have a look at Text::CSV. It might not be necessary, if your data are sufficiently simple, and you might get by with split as GrandFather suggests, but the first time one of the values contains an embedded comma or breaks your assumptions in some other weird way, you'll have a bug, and at that point you'll end up switching to using the CSV-parsing module to fix the bug. If that's at all likely, wouldn't it be easier to just use the module in the first place?
Of course, if you have control over the way the data are generated, then you may be able to guarantee that will never happen, in which case split is fine and Bob is your uncle.
