An input record separator (found in Perl's variable `$/` and usually set to `\n`) determines the end of a line ('record') when reading from a file--like you were doing in your `while` loop. It's kept on the end of the line, unless you do something like `chomp`ing the line. In your case, not removing the input record separator produced undesirable results in your final output. (Sometimes, however, the very last line of a file may not terminate with an input record separator, because the line ends at the end of the file.)	[reply] [d/l] [select]
