PIC18F458 LED AND VFD examples

[dvlee]

Hi,
Im trying to get a PIC18F458 dev board to say something, anything! I started first with a VFD and now have scaled back to a simple LED program.
Have 2 source codes. Can someone point out where the encoding is at fault and what it should be?
Appreciate.

LED:
//05-03-12 LED TOGGLE
#pragma code InterruptVectorHigh = 0x2008
#pragma code InterruptVectorLow = 0x2018
#pragma code main = 0x2020

#include "H:\PROGRAMS AND MCU'S\PIC\PIC 18 2376 PROJECT\header files\lcd.h"
#include "H:\PROGRAMS AND MCU'S\PIC\Microchip\mplabc18\v3.41\h\xlcd.h"

#define key PORTDbits.RD1 /* PORT for key */
#define TRIS_key TRISDbits.TRISD1 /* TRIS for key */

void delay (void)
{
Delay10KTCYx(100);
}
void toggle(void)
{
if(LATB == 0xff)
LATB = 0;
else
LATB = 0xFF;
while(key) delay();
}
void main (void)
{
/* Make all bits on the Port B (LEDs) output bits.
/* If bit is cleared, then the bit is an output bit.
*/
TRISB = 0;
TRIS_key =1;

while (1)
{
if(key == 1) toggle();

}
}

VFD:
