INT 21H
MOV DL,BL
INT 21H

Answer 1

MOV AL,CL
MOV AH,0 ;xor ah, ah looks much better
JMP DEF ;!!!!!!!!!!!!!!!!!!!!!
I DB 10 ;Later this memory was read and understood as operation. now it is data.
DEF: ;!!!!!!!!!!!!!!!!!
DIV I
MOV BL,AL
MOV BH,AH
ADD BL,48
ADD BH,48
;in this case number is reversed
MOV AH,02
MOV DL,BH ;change bh on BL
INT 21H
