       Type: Subroutine
   Category: Maths (Arithmetic)
    Summary: Calculate R = XX and (A P) = Q * A
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * STARS6 calls MUT1


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

   R = XX
   (A P) = Q * A


.MUT1

 LDX XX                 \ Set R = XX
 STX R

 JMP MULT1              \ Jump to MULT1 to do the following:
                        \
                        \   (A P) = Q * A
                        \
                        \ and return from the subroutine using a tail call
