title: Assembly, printing ascii number
body: <p>I have a problem with my assembly code. I want to print number stored in register cx, but when i tried to print it, it printed ascii character instead of ascii number, so I decided to write a procedure to convert ascii char to ascii value. 
  Problem is, that when I try to call that procedure, the program freezes and I have to restart dosbox. Does anyone know whats wrong with this code? Thanks.</p>
  
  <pre><code>P4      PROC                
              MOV AX,CX           ;CX = VALUE THAT I WANT TO CONVERT
              MOV BX,10           
      ASC2:
              DIV BX              ;DIV AX/10
              ADD DX,48           ;ADD 48 TO REMAINDER TO GET ASCII CHARACTER OF NUMBER 
              PUSH AX             ;SAVE AX
              MOV AH,2            ;PRINT REMAINDER STORED IN DX
              INT 21H             ;INTERRUP
              POP AX              ;POP AX BACK
              CMP AX,0            
              JZ EXTT             ;IF AX=0, END OF THE PROCEDURE
              JMP ASC2            ;ELSE REPEAT
      EXTT:
              RET
      P4      ENDP
