title: Unknown opcode skipped: 66, not 8086 instruction - not supported yet
body: <p>I'm using emu8086. I've a question which tasked me to display what we see on seven segment displays after converting from its hexa inputs. I should input my data in hexa, if it matches the hexa input of the seven segment table, it displays the decimal number, eg. 3FH = 0, 06H = 1. I'm using array to implement this program. Below is the working source program:</p>
  <pre><code>ORG 100H     
  
  MOV AL,[1840H]   ；input in this memory location
  MOV CL,0AH       ; initialize length counter
     
  AGAIN:  CMP AL,MSG+BX     ; compare to check if the data matches
          JE RESULT         ; jump to RESULT if data matched
          INC BX            ; increase decimal output by 1 if data not matched
  LOOP AGAIN
  
  MOV [1841H],0FFH          ; display FF if no data matched the array
  
  HLT
  
  MSG DB 3FH, 06H, 5BH, 4FH,66H, 6DH,7DH,07H,7FH,6FH        ; my array with hexa inputs
  
  RESULT: MOV [1841H],BL                 ; display data if matched
  </code></pre>
  <p>I had this program working. But I've tried something which I switch my array <code>MSG DB 3FH...</code> to a position after <code>ORG 100H</code> and before <code>MOV AL,[1840H]</code>, running the program will give an error message</p>
  <blockquote>
  <p>&quot;Unknown opcode skipped: 66, not 8086 instruction - not supported yet&quot;.</p>
  </blockquote>
  <p>I can't find the reason why.</p>
  <p>Anyone would have any idea what's the reason and can I fix anything to make my program work if I were to keep the array between <code>ORG 100H</code> and <code>MOV AL,[1840H]</code> ?</p>
