No, it not that. Here is my current program:
#include <p18cxxx.h>

#pragma config WDT = OFF
#pragma config OSC = INTIO67

void delay (void)
{
  int i;

  for (i = 0; i < 10000; i++)
    ;
}

void main (void)
{
  /* Make all bits on the Port B (LEDs) output bits.
   * If bit is cleared, then the bit is an output bit.
   */
  int mylatd;

  TRISD = 0;
  LATD = 3;
  mylatd=3;

  while (1)
    {
      /* Delay so human eye can see change */
      delay ();

      /* Light the LEDs */
   mylatd++;
      LATD = mylatd;
    }
}
