Assembly - how to increase a variable by 2

How do I increase a variable by 2? I am using Assembly x86 and TASM.

Thanks for help.

Solution

  • Try this :

    .stack 100h
.data
  my_var dw ?
.code      
  mov  ax,@data
  mov  ds,ax

  mov  my_var, 5
  add  my_var, 2         ;<=== INCREASE BY 2 ( 5+2 ).

  mov  ax,4c00h
  int  21h

    If you are using IDEAL mode :

      add  [ my_var ], 2     ;<=== INCREASE BY 2 ( 5+2 ).
