Answer to Question #241327 in Assembler for xyz

Question

Write a assembly program that takes two 2-D matrixes A and B. Add value of the matrixes and store it in different matrix called C. NB: Implement the above problem inside Main Procedure.

Answer 1

TITLE  matrix:  C = A+B
INCLUDE Irvine32.inc

.data
AA  BYTE  2, 3
    BYTE  4, 5

CC  BYTE  4 DUP(?)

msgA    BYTE "MATRIX A: ",0AH,0DH,0
msgB    BYTE "MATRIX B: ",0AH,0DH,0
msgC    BYTE "MATRIX C=A+B ",0AH,0DH,0
