      Notes:    The ABSOLUTE and INTERRUPT calls use the register buffer
                before they make the call and after the call is complete,
                the contents of the register buffer are up-to-date with
                the current register values.

                If register is not in the range 0 to 9, runtime error 5
                (Illegal Function Call) occurs.
