title: How to output a value stored in a variable in assembly 8086?
body: <p>I am learning assembly programming using "8086 emu" (Its a software program . Emulator .) I am evaluating a basic expression -  </p>
  
  <p><strong>a=b+c-d*e</strong> </p>
  
  <p>My problem is that when I am using int 21h to take in values , Its taking only single digit (character) as input for each variable .  </p>
  
  <p>Also after the evaluation , I am <strong>unable to print the value stored in the variable 'a' on the output screen</strong> . </p>
  
  <p>Can anyone give a solution for both the problems ?</p>
