What am I doing wrong?

#include <p18f4455.h>
#pragma config WDT = OFF

#define B0 0;

void delay (void)
{
int i;
for (i = 0; i < 10000; i++);
}

void main(void)
{
while (1)
{
output_high(PORTB_RB0);
delay();
output_low(PORTB_RB0);
delay();
}
}

// All I want to do s toggle RB0 with a small delay. keep getting the following error.

// I have checked and made sure that PORTB & RB0 are definded but still get the error. I'm new to C programming. Any ideas would be great.

I'm just learning C18 so I might not be much help. Still, I'm curious, are output_high and output_low library functions? I can't find them. And how did you come up the the PORTB_RB0 construct? I've only learned how to toggle bits so far using something like this;

Thanks Mike

As I stated before I'm also very new to C programming aswell.

I managed to get it to go using the code;

PORTBbits.RB0 = 0;

Looks like PORTB_RB0 is not defined?
