## The `onExecute' callback

Event number: 44
Generated for: APL (child task) object

The `onExecute` callback is invoked in an `APL` object belonging to a parent task when the child task is about to execute an expression or command (either typed by the user, or invoked under program control using the `Execute` method).

During the callback, ŒWARG contains the command or expression which is about to be executed, as a character vector. This can be used for example to write an APL tutorial application when the parent task can see what the user is entering in the child-task session window.

The event-specific parameters in ŒEV are (in index origin 1):

            ŒEV[6]         Task ID for the child task

See the section on APLX Multi-tasking for more details.
