Question

DATA SEGMENT
TABLE DB 00H,01H,04H,09H,16H,25H,36H,49H,64H,81H
RSLT DB ?
STRING DB 'please enter a number:','$'
STRING1 DB 0DH,0AH,'the result is:$'
DATA ENDS

STACK SEGMENT STACK
DB 100 DUP(?)
STACK ENDS

CODE SEGMENT
ASSUME CS:CODE, DS:DATA
START:
MOV AX, DATA
MOV DS, AX
LEA DX,STRING
MOV AH,09H
INT 21H
MOV AH,01H ;接受一个字符，并回显
INT 21H ;注意：如果是mov ah，00h 则是int 16h
AND AL, 0FH
XOR BX, BX;清零
MOV BL, AL
LEA SI, TABLE
MOV AL, [SI+BX];输入一个数
MOV RSLT, AL

LEA DX,STRING1
MOV AH,09H
INT 21H


MOV DL,RSLT
CMP DL,9
JG NEXT1
JNG NEXT2

NEXT1:
MOV BL,DL
MOV CL,4
SHR DL,CL
ADD DL,30H
CALL NEXT3

MOV DL,BL
AND DL,0FH
ADD DL,30H
CALL NEXT3

MOV AH, 4CH
INT 21H

NEXT2:
ADD DL,30H
CALL NEXT3

MOV AH, 4CH
INT 21H

NEXT3:
MOV AH,02H
INT 21H
RET

MOV AH, 4CH
INT 21H

CODE ENDS
END START
