hiGetUserAbort( ) 
=> t / nil 

Description

Aborts a procedure when Ctrl+C is pressed.

This function also updates the tumbling dice cursor. In procedures that are compute-intensive, you should call hiGetUserAbort at least once a second to update the cursor and inform the user that processing has not stopped.

Normally, if the function returns t, you should abort processing and return control to the user.
