  This is not efficient, but it should be clear and should work.
  
  If you want to convert your Word value to "volts" with decimal, you'd need to supply more info (like what range of values is your ADC giving you)
  

  chars VAR Byte(5)
  val VAR Word
  idx VAR Byte
  
  chars(4) = val/10000 ' ten thousands
  chars(3) = val//10000 
  chars(3) = chars(3)/1000  ' thousands
  chars(2) = val//1000
  chars(2) = chars(2)/100 ' hundreds
  chars(1) = val//100
  chars(1) = chars(1)/10  ' tens
  chars(0) = val//10 ' ones
  
  FOR idx = 0 TO 4
      chars(idx) = chars(idx) + "0" ' convert to ascii char
  ENDIF
  
  ' now if you dump chars(0)...char(4) to an LCD, you'll have a 5 digit number that shows val

  I am so new at this; I am used to using PBASIC. Thank you ZOOT for the info I completely forgot that I can use a WORD modifier. I am also trying to learn ASM, and that is where I got confused. I thank you for your time.

  The sample I put up is pretty "Pbasic-ish". As I said, it is not very efficient, either cycle-wise or codespace-wise. At the least, division and modulus should really be wrapped inside functions to save space.
