    Try the config line I posted above. What you're trying to do here isn't any good.

    Okay...I now understand what is to be done, and the changes were made as you said to the .inc file. Compile is now error free. Pop-up window settings are now as per your suggestion. Sorry for the crazy rookie mistakes. Let's see what happens now....

    Update...LED is on steady. No blinking

    You might want to try something like this to see your LEDs blink;
    Code:
    DEFINE OSC 4 
    @ __CONFIG _INTRC_IO & _WDT_OFF & _PWRTE_OFF & _LVP_OFF & _MCLR_OFF & _BODEN_OFF & _DEBUG_OFF
    OSCCON = %01100000  ' 4MHz 
    ADCON1=7 
    TRISA = %00000000 
    TRISB = %00000000 
    TRISB.4 = 0 
    TRISA.0 = 0 
    PORTA.0 = 0 
    PORTB.4 = 0 
    
    LOOP: 
      PORTB.4 = PORTB.4 ^ 1
      PAUSE 250
      PORTA.0 = PORTA.0 ^ 1
      PAUSE 250 
      Goto LOOP
    Check your PBP manual to see why your LEDs aren't visibly blinking with PULSEOUT...;o)
