NUMBER will copy over a text file, adding line numbers to all 
non-blank lines and adding a newline after each line in the source, blank 
or not.  Useful for putting a single-spaced manuscript in an 
easy-on-the-eyes format for editing.

        The usage is NUMBER sourcefile [destination file].  If the 
destination file is omitted, the output is sent to the screen.  The output 
file can be LST: to send output to the printer.  Drive/user specs or ZCPR3 
named directory references can be used on both filenames.
