write a program to sort a array in ascending order in Assembly Language
Code:
name "Assending order array"
.model small
.stack 100h
.data
msg db 0dh,0ah,0ah,"Number List : $"
msg1 db 0dh,0ah," Sort : $"
msg3 db 0dh,0ah,0ah,"NAME: Usama Qasim $"
msg33 db 0dh,0ah,"Roll: 17251519-015 $"
msg4 db 0dh,0ah,0ah,"NAME: Umair Idrees $"
msg44 db 0dh,0ah,"Roll: 17251519-034 $"
msg5 db 0dh,0ah,0ah,"NAME: Sheraz Ahmed $"
msg55 db 0dh,0ah,"Roll: 16171519-072 $"
array db 5,3,9,0,2,6,1,7,8,4
