Synopsis
Official Name: Mon
BCALL Address: 401E
Starts the system monitor. The system monitor will take over the system, and report events to the application via the monitor vectors. The application must set its own monitor vectors with AppInit before calling Mon. Control of the application will never be returned from Mon.
Inputs
- AppAllowContext, (IY + APIFlg) = 1 to allow Mon to pass context keys, like kYequ to the cxMain routine.
- CurLock, (IY + curFlags) = 1 to lock the cursor off
Outputs
- none
Registers Destroyed
- Doesn't Matter because It doesn't return
Comments
The system NEVER returns from this B_CALL. The programmer should find alternative methods of regaining control and exiting such as hooks, cxMain, etc.
