The event Error occurs when a M[UMPS] error is detected and this error is not handled within any localized error trap in the code of the application.
At the window level, completion of the action logic with the M[UMPS] command Quit will cause resumption of event handling for the window. Use of either of the macros %%Return or %%Cancel will cause a return from the window.
Including the macro %%NotOK before a Quit from the Error section will cause the error to be passed back to the section that called the window.
