The carriage return is Ascii 13. However, what we DOS users
commonly refer to as a "carriage return" or "" or "CrLf"
actually consists of two Ascii characters, 13 and 10, a carriage
return followed by a line feed. Therefore, the carriage return
displayed in XyWrite and most other programs as a single character
is actually two bytes in length.

There must be a dozen ways in XPL to test for a CrLf at the end of a
line. Here is an easy one. The procedure is to DeFine the current
line (func DL), then SEarch within the DeFined text (SE/S) -- i.e.,
within the current line -- for a carriage return. If it's found,
the line ends in a CrLf. Here's the code:
