You know, I think I did not understand what Bruce was trying to explain to me in the old thread. Because this does compile for the PIC18F4520
Code:
asm
    __CONFIG    _CONFIG1H, _OSC_HS_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
    __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
    __CONFIG    _CONFIG3H, _CCP2MX_PORTC_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
    __CONFIG    _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L
endasm
 
;@ CONFIG OSC = INTIO67 ;config for internal osc
;@ CONFIG PBADEN=OFF ;turn of port b analog inputs
;@ CONFIG MCLRE=ON ;activate master clear
;@ CONFIG WDT = OFF ;turn off watchdog timer
;@ CONFIG STVREN = OFF ;turn off reset on overflow/underflow
;@ CONFIG LVP = OFF ;turn off low voltage programming
Include "modedefs.bas"
define OSC 32
OSCCON = %01110000 'set internal oscillator to 8 mhz and select it as system clock
OSCTUNE= %11000000 'turn on pll frequency is now 32
INTCON = %00000000 'turn off all interupt functions
ADCON0 = %00000000 'turn off adcs set to digital i/o 
ADCON1 = %00001111 'turn off adcs set to digital i/o
TRISA = %00000000 'set port A to all outputs
TRISB = %00000000 'set port B to all outputs
TRISC = %10001011 'set port C 
TRISD = %00000000 'set port D to all outputs
TRISE = %00000000 'set port E to all outputs
PORTA = %00000000 'set all outputs on port a to 0
PORTB = %00010000 'set outputs on port b to 0
PORTD = %00000000 'set all outputs on port d to 0
PORTE = %00000000 'set all outputs on port e to 0
WDTCON = %00000000 'turn off wdt
So, I guess if you convert your configs to the style above you will be ok?
