title: an issue in Assembly using Emu 8086 , jump not working
body: <p>i just start on making my project for university for  flipping card game, 
  using emulator from emu8086.com</p>
  
  <p>sadly i got stuck on such a early stat .</p>
  
  <p>somehow can't quite figure out whats wrong .</p>
  
  <p>the jump using JZ or JE , should work if i use cmp on 2 equal value , but it is not working .</p>
  
  <p>nothing happening ! i used </p>
  
  <pre><code>mov ah,1
  int 21h
  
  cmp al,1 or cmp al,'1'
  JE or JZ  Card1
  </code></pre>
  
  <p>but it is not jumping no matter what i write ,</p>
  
  <p>my full code :</p>

  <p>i left the sample codes from making a new file in emulator in my code , will remove them later.</p>
  
  <p>u see i put AL into AH and used it too , just coz i couldn't  figure whats wrong ,
  but it didn't work when i used AL itself in cmp either</p>
  
  <p>non of the JE / JZ jumps work , only the JMP one work .</p>
  
  <p>Tnx.</p>
