I am using a PIC16F874. When I program the PIC it shows the error-There are more program codes at <EEO> after <EDF>.

Some part of my code doesnot work.is it due to this?
How do i fix this??
thanx
marc
my code:

// You must include the header file for the PIC
#include <16F874.H>

// Setting the number of Hz the PIC is at
#use delay(clock=20000000)

// Initializing variables
char event;
int distance, count;
float temp;

void main()
{
enable_interrupts(INT_rb);
enable_interrupts(global);
output_low(PIN_E0);
count = 0;


while(1){

if(event == 's' || event == 'r' || event == 'g' || event == 'h'){
while(event == 's')
{
count = 2000;
//motor forward
output_high(PIN_D3);
output_low(PIN_D2);
delay_ms(1);
//count = 1000; // worked with 0


}



if(event == 'g')


{
//Turn transmitter on
output_high(PIN_E0);

temp = 9*((4000 + count)/(2000));
distance = (int) temp;

switch(distance) //outputting data to wireless

"Urgent" probably means homework. But here's one small tip:

You have tons and tons of code which outputs the 'distance' to Port C.
Why not just do it with one line of code ? Like this:

Code:
output_c(distance);

Yep it's getting to the end of the school year and this board will be expected to do term papers. Many might think that due to the large number of repetitive questions ( Ex RS232 issues) that the search function on this board must be broken.
