For single-player games, an example define options block looks like this:
define options debug on panes on end define
The available options are:
abbreviations [ on | off ]
Specifies whether players are allowed to use abbreviated object names in their commands. By default, this is on. This allows players to be able to type "look at pic" instead of "look at picture".
debug [ on | off ]
Specifies whether the "Debug" menu appears. This is useful for released games where you don't want players peeking into what's going on - particularly useful for compiled games where this statement can't be removed by the player.
panes [ on | off | disabled]
Specifies whether the panes on the right-hand side of the Quest window are on, off, or completely disabled. If on or off, the player can toggle whether panes are displayed. If displayed, the button is removed and panes do not appear.
