   END OF SEASON PROGRAM FOR FOOTBALL REXX SUITE
  -----------------------------------------------
                   Copyright  Mark Naughton 1997


Version    Date     History
--------------------------------------------------------------------------
 1.0       061097   First release - after about 10 days and loads of
                    hassle and numerous variations in the method for
                    swapping/deleting teams between divisions.
           250899   Added error msg to file checks.
           110999   Converted to use locale. Some error messages, before
                    reading the locale, will still be in English.
           190999   Added support for subdirectories in "Data/".
           220500   End of season didn't quite work for the new directories
                    as reported by Kevin Lambert - thanks mate - bug fixed.

**************************************************************************

Procedure
---------

1. Check files exist.
2. Read number of divisions and divisions. Then store.
3. Search all leagues/divisions to see if all matches have been played,
   if not, then give error and exit.
4. Create all league/division tables and save to temporary files.
5. Display the winner, teams relegated and teams promoted for each
   division.
6. Loop. Read teams from division then swap/delete those teams that have
   been relegated/promoted between adjoining leagues/divisions. Write to
   temporary file when complete. End loop.
7. Loop. Read previous '.df' file and using data from temporary files
   created in (6), create '_NewData.df' files for each league/division.
   End loop.
8. Display message about '_NewData.df' files.
9. Display final league/division tables.
10.Erase temporary files. Exit.
