Re^2: Can't use an undefined value as an ARRAY referenceby Anonymous Monk |

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!
