Program for sorting an array for 8086

1.Ascending order

Aim:

To write an assembly language program to arrange the given numbers in ascending   order.

Tools:

PC installed with TASM.

Program:

ASSUME CS : CODE, DS : DATA
CODE SEGMENT
MOV AX, DATA
MOV DS, AX
MOV DX, COUNT - 1
BACK : MOV CX, DX
MOV SI,OFFSET LIST
AGAIN : MOV AX, [SI]
CMP AX, [SI + 2]
JC GO
XCHG AX, [SI + 2]
XCHG AX, [SI]
GO:INC SI
INC SI
LOOP AGAIN
DEC DX
JNZ BACK
HLT
CODE ENDS
DATA SEGMENT
LIST DW 05H, 04H, 01H, 03H, 02H
COUNT EQU 05H
DATA ENDS
END

Result:

Input:

LIST (DS : 0000H) = 05H, 04H, 01H, 03H, 02H

Output:

LIST (DS : 0000H) = 01H, 02H, 03H, 04H, 05H
