       Type: Subroutine
   Category: Maths (Arithmetic)
    Summary: Calculate (S R) = XX(1 0) and (A P) = Q * A
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * STARS1 calls MUT2


 Do the following assignment, and multiplication of two signed 8-bit numbers:

   (S R) = XX(1 0)
   (A P) = Q * A


.MUT2

 LDX XX+1               ; Set S = XX+1
 STX S

                        ; Fall through into MUT1 to do the following:
                        ;
                        ;   R = XX
                        ;   (A P) = Q * A
