  You have to declare the subroutine BEFORE you try to use it.
  
  If you want to have declared subroutines in an interrupt you just make the interrupt a simple GOTO.
  
  Like so:

  DEVICE SX28, OSCHS3, TURBO, STACKX, OPTIONX
  FREQ  50_000_000
   
  PIEZO VAR RB.1
   
  X VAR BYTE
   
  INTERRUPT
    GOTO HandleInt
   
  CRICKET SUB
   
  HandleInt:
    WKPND_B = X
    IF X = %00000001 THEN
      CRICKET
    ENDIF
    WKPND_B = %00000000
  RETURNINT
   
  PROGRAM Start
   
  Start:
    WKED_B = %11111110
    WKEN_B = %11111110
    TRIS_B = %00000001
    WKPND_B = %00000000
    X = 0
   
  Main:
    SLEEP
   
  CRICKET:
   FREQOUT PIEZO, 14, 4500
   FREQOUT PIEZO, 11, 4200
   FREQOUT PIEZO, 14, 4500
   FREQOUT PIEZO, 11, 4200
   FREQOUT PIEZO, 14, 4500
   FREQOUT PIEZO, 11, 4200
   FREQOUT PIEZO, 14, 4500
   FREQOUT PIEZO, 11, 4200
  RETURN
  

  
  Please DO use the template in your programs, I just removed it so it would be shorted to post.

  You're overlooking the latest version of SX/B!
  
  1.42.01 -- you can get it here: http://forums.parallax.com/forums/default.aspx?f=7&m=54473
  
  If that doesn't fix the problem please post your code and I'll have a look.
