Answer 1

大一时候写的一个打印BX寄存器内容的程序，你可以参考一下：
DATA SEGMENT
DATA ENDS
STA SEGMENT STACK
STA ENDS
CODE SEGMENT
ASSUME CS: CODE, DS: DATA, SS: STA
START: MOV CL, 4
MOV DI, BX
AND BX, 0F000H
MOV DL, BH
SHR DL, CL
CALL ASC
MOV BX, DI
AND BX, 0F00H
MOV DL, BH
CALL ASC
MOV BX, DI
AND BX, 00F0H
MOV DL, BL
SHR DL, CL
CMP DL, 000AH
CALL ASC
MOV BX, DI
AND BX, 000FH
MOV DL, BL
CALL ASC
JMP EXIT
ASC PROC
CMP DL, 000AH
JNB CHG
ADD DL, 30H
JMP DIS
CHG: ADD DL, 37H
DIS: MOV AH, 2
INT 21H
RET
ASC ENDP
EXIT: MOV AH, 4CH
INT 21H
CODE ENDS
END START

Answer 2

应该很复杂
