Hi to all engineers,

I wrote simple led test code for microchip demo board2
it works but when I move main () function to top it generates
an error why?
Any help will appreciate. Hitech support said I didn't
Define port_init () function but I do not get it.

#include <pic18.h>
#include "delay.c"
#define PORTBIT(adr, bit)       ((unsigned)(&adr)*8+(bit))
static bit      led1  @ PORTBIT(PORTB, 0);
static bit      led8  @ PORTBIT(PORTB, 7);

// led right,left test funtion

         TRISA=1; // set portc all input
         PORTB=0; // make sure all leds off
         }

// main program

{
    port_init();        // setup port
    ledrl();       // call led funtion
}
