How to set 18F2520 for INT OSC?

When you said you were not using a crystal I got to thinking resonator.
You can use HS mode, OSC2 will just be an open pin.

As for your problem I am at a loss.
Maybe there is something at the beginning of your code messing things up?

This is my entire program, and I get a 25 sec. delay until the LED goes on.

ASM
     ;PORT A 
     CLRF PORTA 
     MOVLW 07h 
     MOVWF ADCON1                           ;A/D'S OFF 
     MOVWF 07h 
     MOVWF CMCON                            ;COMPARATORS OFF  
     MOVLW 00000000b                        ;PIN DIRECTION PORT A  
     MOVWF TRISA 
ENDASM

DEFINE OSC 20                                
LOW PORTA.6                                     'TURN LED ON
STOP

Thanks anyway, Dave!
