Nothing should be put after the "autocoach" or "noautocoach", nor is the
usual "done" required. Setting autocoach will set the computer to submit
coaching orders immediately before each game. Running noautocoach will
unset the autocoach setting, so that you will once again run the team
yourself.
Essentially, this is a choice of convenience versus control for your team.
If you are going to be gone for the start of a season, you may want to
set this so that your team will have coaching orders.
