Set the value Multiple Data Communications (MDC) generation target; this
                  	 becomes the value of the &APS-MDC built-in function, which holds the data
                  	 communications target value. This function in the control file is passed to the
                  	 MFG. In your rule program logic, examine this variable to tailor the output to
                  	 the generated screen.
