   SCHEDULER PROGRAM FOR FOOTBALL REXX SUITE
  -------------------------------------------
                   Copyright  Mark Naughton 1996


Version    Date     History
--------------------------------------------------------------------------
 1.0       090996   First release.
           180996   Changed record-count so that it is stored in element
                    zero of each array. Deleted some variable assigns
                    that weren't needed. Amended reading into arrays so
                    that the count is set correctly for one element.
                    Removed all "call "references before library routines.
           270996   Added code to sort 'Teams.df' and to recreate it.
                    Changed a few messages and tidied up.
           ******   Decided not to store goalscorers. Was not viable as
                    too much data would have to be collected.
           270996   Added code for points_per_draw and points_per_loss.
                    Now uses DOS Delete command, not the support function.
                    Amended reading in of teams - quicker, tidier. Added
                    code to display a report on the league. Updated to
                    use new filenames. Improved error messages. Added
                    error check for more than 1000 matches.
 1.1       131196   Added argument so it can become a component of
                    FOOTBALL. Removed all messages. Added checks for
                    files - if not found, exits without a message.
                    Rewrote report.
           201196   Added code to store relegation. All this will do is
                    display a line across the league table. Amended msg
                    for play_each_other. Added code to allow teams to
                    play each other more than twice.
           201196   Decided not to implement PreviousPosition as it would
                    require file changes and a reformat of the league
                    table. It may be implemented soon though.
           211196   Updated and tidied the display.
           201296   Fixed bug where if the number of times that each team
                    play each other is an even number, then its not set
                    to the correct value (only works for odd matches).
           110197   Blanks are now removed from the filename, before
                    creation.
 1.2       110497   Added code to support Points_Per_Goals.
 2.0       010997   Have been working on Scheduling for about a week. Put
                    in code and now ready to test.
           030997   Problem with format of '.sf' file - fixed. Program
                    failed due to missing 'do' - fixed. All works.
           050997   Added extra '*' at end of '.sf' file in line with
                    manual created one.
           070997   Fixed bug for AUTOSCHED - no. of matches in report was
                    wrong - needed to be reset before the loop.
           220997   Added code for promotion and divisions.
           240997   Removed all data such as teams count, points per win,
                    relegation etc, as they are already stored in '.df'.
           250997   Wasn't creating the files - traced to resetting the
                    strings that were used to pick the number of divisions
                    and the divisions themselves, to the variables that
                    are used as the assignments/counters. Made amendments
                    to display of the report.
           151297   Tidied display.
           240898   Amended code that regenerates .df file as it was
                    adding two blank lines before the teams and causing
                    it to fail.
           210499   Scheduler now tidies up previous files, ie. deleting
                    a '.sflearn' file from a previous league.
 2.1       050599   Added code to check the schedule file to see if it
                    contains enough matches for the league to be played
                    with the specified settings. Added support for playing
                    teams an odd number of times and for schedules with
                    teams playing it each other more than twice.
                    Enhanced a few messages.

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

Procedure
---------

1. Check files exist.
2. Read 'Teams.df' and write teams to output file.
3. If AutoSched is specified then store parameters.
4. Using external program, sort the teams.
5. Re-read the teams and recreate 'Teams.df'.
6. Open 'Teams.df' for reading.
7. Extract data and store.
8. If no separator in it, then take it as a
   team. Strip blanks and store.
9. Close input file.
10.IF AUTOMATIC - Read specified schedule file.
11.Read schedules and store dates/weeks.
12.Give error if the number of teams does not equal
   the number of lines in the schedule file.
13.Write the dates/weeks to a file then use an
   external program to sort them, writing back to the file.
14.Read dates into array and delete file.
15.Format dates array with season start date.
16.Format and write '.sf' files.
17.IF MANUAL - Open 'Teams.sf' file.
18.Write league name to it.
19.Loop and write all teams with a schedule of
   all other teams. Number of matches is stored.
20.Close output file.
21.Open 'Teams.stats' for writing.
22.Write all data such as PLAYED,WIN,DRAW,LOST,GOALS_FOR,GOALS_AGAINST and
   POINTS for each team.
23.Close file. Delete file (if found).
24.Create a report on the league created and then exit.
