in reply to Text file to a 2D array

I've tried to maintain your variable names, and aimed more for understandability than brevity:

while ($tempData = <DataIN>) { chomp($tempData); $listTemp = []; @$listTemp = split(/,/ , $tempData); push (@listFinal, $listTemp); } return @listFinal;

Read one line at a time, the text of the current line is stored in $tempData. Remove the trainling newline from $tempData.

Generate a new, empty anonymous array, $listTemp is a reference to that array.

Split the line up at the commas, this gives you a list of values. Those are stored in the Array that $listTemp points to.

Now, push $listTemp into the resulting Array.
