1、在内存DATA开始的单元中有数a,b若a大于等于b,则位置不变，否则a,b互换。

DATA SEGMENT
A DB 20
B DB 10
DATA ENDS

STACK1 SEGMENT PARA STACK
DW 20H DUP(0)
STACK1 ENDS

COSEG SEGMENT
ASSUME CS:COSEG,DS:DATA,SS:STACK1
START:
MOV AX,DATA
MOV DS,AX
MOV AH,A
MOV AL,B

上面的错了。不好意思。。。

DATA SEGMENT
A DB 10
B DB 20
DATA ENDS

STACK1 SEGMENT PARA STACK
DW 20H DUP(0)
STACK1 ENDS

COSEG SEGMENT
ASSUME CS:COSEG,DS:DATA,SS:STACK1
START:
MOV AX,DATA
MOV DS,AX
MOV AH,A
MOV AL,B
CMP AH,AL
JGE EXCHG
JMP ENDO
EXCHG: XCHG AH,AL
MOV A,AH
MOV B,AL
ENDO: MOV AH,4CH
INT 21H
COSEG ENDS
END START
