Re^2: Can't use an undefined value as an ARRAY reference by Anonymous Monk on Mar 17, 2010 at 06:08 UTC
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!	[reply]
