...that the `chomp($temp)` would spare me all the nasty newline problems Depends on what's in `$/`. `$/` by default holds `"\n"`. On Windows, the `:crlf` PerlIO layer is responsible for translating `"\r\n"` to `"\n"`. On Unix, this layer is not active (by default), so in case you have input coming from Windows (via cut-n-paste, or whatever), the carriage returns will survive.	[reply] [d/l] [select]

`chomp()` will remove only trailing string that corresponds to the current value of `$/` (`$INPUT_RECORD_SEPARATOR`).	[reply] [d/l] [select]

jevaly: Yep ... in the Windows world, things can be a bit messy. Many Windows users simply replace `chomp $varname;` with `$varname =~ s/\s+$//;` to trim off all trailing whitespace from a variable. NOTE: It's not an exact replacement, so if your code expects whitespace at the end of your lines, you'll probably want to adjust $/ to the proper value for your incoming files. For my purposes, removing whitespace from the end of the string works fine in nearly all cases. ...roboticus	[reply] [d/l] [select]
