Hallo, I have a tab-delimited file in which results are stored from a form. Works fine. But now I want to read this file (it has several fields) in an array, and sort by let say field1, then by field2, then field3. The entries are numeric (integer). BTW. If I have three values for day, month and year each, can I treat a date as ONE variable (and then sort on that date) ? Can someone help me a bit ?
