  <p>it compiles OK, but when I run it, the emu8086 says:unknown opcode skipped: 65
  not 8086 instruction - not supported yet.    at sE   db 'Echo', 20h, '$'.    I am just wondering why this would happen?I have tried to change the name of my variables but it just doesn't work.</p>
  
  <p>The code is too long to paste.</p>
