code not working

Question working on: The program of this exercise deals with arrays of numbers and subroutines. At the beginning of your program you will allocate empty storage for two original arrays and their sorted versions. For the overall program layout, use the program skeleton file (lab2-v32-inA-skl).

Complete the above MSP430 assembly language program where the SORT1 part sets the R4/R5/R6 parameters, which are used by the SORT subroutine to sort array ARY1. R5 holds the starting address of the array. R4 holds the length of the array. R6 holds the starting location of the sorted Array. SORT2 code is similar to SORT1 above using same registers. Arrays are in decimal notation! Sort Arrays in increasing order from lowest to highest value.

The code I have built is this: (italics is what was given at beginning of code) (* errors marked when run)

;Memory allocation of arrays must be done prior to the RESET & StopWDT ARY1 .set 0x0200 ;Memory allocation ARY1 ARY1S .set 0x0210 ;Memory allocation ARYS ARY2 .set 0x0220 ;Memory allocation ARY2 ARY2S .set 0x0230 ;Memory allocation AR2S ;------------------------------------------------------------------------------- ; Main loop here ;-------------------------------------------------------------------------------
