 Description

     DOS reacts to errors in several ways.  One of the best known and least
     preferred by programmers is the question:  "(A)bort, (R)etry, (I)gnore".
     ERRORACT() tells you how the application should react to the last DOS
     error that occurred.

 Example

     Show an error that requires the program to terminate:

     nAction  :=  ERRORACT()
     IF nAction = 4
        ? "Unfortunately, the program must be terminated!"
        QUIT
     ENDIF
