Newbie question: How to update the status file of an already-created game?

Hi. I'm a reasonably experienced Diplomacy player but totally new to the DPJudge. I hope you'll forgive this total newbie question, but how do you update the status file of an already-created game? The email commands page says:

"Once he receives the e-mail reply to the CREATE command, the Master also has an opportunity to modify the game status file in any way, altering, deleting, or supplementing any lines he may have provided beneath the CREATE command. Again, consult the status file directive list for details on updating a game status file."

That section links to a page with a list of possible parameters one can set, but doesn't (from what I've been able to tell) explain exactly how to implement those parameters. I'd be really grateful for just some basic assistance on this. Thank you so much,

David
