To enter a program source file into the project, the user can modify the main.asm program
or enter his or her program with a different name and add it to the project. Using the second
approach, the user must remove the main.asm file from the project.
In this section, we use the following assembly program to illustrate the project build and
debug process:

include “c:\miniide\hcs12.inc”

ARCNT equ 20

org $1000

sum ds.w 1

average ds.w 1

icnt ds.b 1

org $1500

start movw #0,sum

movb #ARCNT,icnt ; initialize loop count

ldx #array ; use X as a pointer to the array

addloop ldd sum ; add array[i] to sum and move pointer

addd 2,x 1 ; “

std sum ; “

dec icnt ; decrement loop count

bne addloop ; not done yet?
