Required Scripting Component Routines

Manipulating the Active Function

The OSASetActiveProc and OSAGetActiveProc functions allow your application to set or to get a pointer to the active function called periodically by the scripting component during script execution. To get time periodically during script execution for its own purposes, your application can substitute its own active function for use by the scripting component. If you do not specify an active function, the scripting component uses its default active function, which allows a user to cancel script execution.

The functions described in this section use the following type for pointers to active functions:

TYPE OSAActiveProcPtr = ProcPtr;

For more information about active functions, see "Supplying an Alternative Active Function" on page 10-23.
