*** error 65: access violation at C:0x0100 : no 'execute/read' permission

HAUNING CHIU

I am new to c and keil. When I try to debug my code, this error message appeared. May anyone help me to find out where I got wrong?
Thanks a lot.

Here is my code:

#include <reg51.h>
#include "IOPort.h"
unsigned char pulse1[]={9, 3, 6, 12};
unsigned char pulse2[]={2, 3};
unsigned char pulse3[]={0, 1};

delay(int d)
{

int i;
for (i=0;i<d;i++);
}

forward ()
{

int j,c,no;

for (c=0;c<25;c++)

{

no=1;

for (j=no;j>=0;j--)

{

P1 = pulse2[j];

delay(1000);

}

}

}

main()
{

forward();
}

    Thanks for your reply.
    I really don't know a program need to be terminate.
    I think I should study how to use c language again.
    And, actually I had google it before, though I still can't figure out how to debug my code... I think the reason is that I don't have enough background knowledge.
    Again, thank you.
