You can edit the CALENDAR file with a DOS editor. The first two sets of
numbers are the race dates. The third number tells whether the race is
the first or second race at a particular track (0 for the first race, 1
for the second race). The last number is a night or day race (0 for
night, 1 for day). Finally, the name of the track has to match the name
of the particular track's *.dat file in the /TRACKS subdirectory.
Example: 5 30 0 1 CHRLTTE
This would be for a race at C***te on May 30. It is
the first race at
at this track during the season. It is a day race.
