First hint: the statement `<FILE>` reads the contents of FILE until the next newline, `chomp` removes that trailing newline, so as a result `$_` will not contain any newlines afterwards. So your splitting on newlines makes no sense as neither `$first` nor `$second` (being parts of `$_`) will contain any newline.	[reply] [d/l] [select]

Use Basic debugging checklist and Dumper() all the variable in play ( $_, $first,$second ) and you'll have your answer	[reply]

New words, same old question: "How do I debug a problem?" Answer: read the replies to your numerous similar questions. If you didn't program your executable by toggling in binary, it wasn't really programming!	[reply]
