You might also find 'use diagnostics;' useful - put this at the top of your program and it'll give you more explainey error messages.

    Hello, if $dataSet{results} is parsed from a user input file for example, and we would want to give user the flexibility of defining and not defining this array depending on their applications, is there a way I could get around this without getting the error of "undefined value as an ARRAY reference" ? Thanks!
