I have an indexing problems-CodePudding

I need to write names from keyboard and then display them, one on each line. They should be displayed with an index before of them. For example if I write the names elena and maria the should be displayed as 1.elena 2.maria

I tried adding a counter variable but I have some errors when I try to run the program in DosBox. Can someone help me? Here is my clean label that is outputting the names:

 lista:
  mov  dx, offset nume
print_names:
push dx
  mov  dl, 13          ; carriage return
  mov  ah, 02h
  int  21h
  mov  dl, 10          ; linefeed
  mov  ah, 02h
  int  21h
  pop  dx
  mov dx, offset index
  mov ah, 9
  int 21h
  inc byte ptr index
  mov  dx, offset nume
  mov  ah, 09h
  int  21h
  ; (*)
  add  dx, 5   1
  cmp  dx, numePointer ; check if the current name is the last one
  jb   print_names
  jmp  bucla           ; return to main loop

CodePudding user response：

The addition is destroying the DX pointer for the name to be displayed!
Why did you put the additional code between proc endp?
punct db '.' ,10, '$' does not need the 10. Should be punct db '.$' or even better, combine it with index like in index db '?.$'.
And still better, combine the newline with it too:

lista:
  mov  dx, offset nume
print_names:
  push dx                        ; (1)
  mov  dx, offset numeIndex
  mov  ah, 09h
  int  21h
  inc  byte ptr [numeIndex   2]  ; "1" -> "2" -> "3" ...
  pop  dx                        ; (1)

  mov  ah, 09h
  int  21h
  add  dx, 5   1
  cmp  dx, numePointer ; check if the current name is the last one
  jb   print_names
  jmp  bucla           ; return to main loop

  ...

numeIndex db 13, 10, 49, 46, 36
