The Copy Spooled File 3 command splits a spooled file into multiple spooled
files based on a change in value of the data at a specific line and position of
each page. Assume you have a report by salesman for all salesmen and want to
split the report so there is separate spooled file for each salesman. The
salesman number must be listed at the same location on each page, but does not
have to be on the first line.
