sine wave PWM

I would like a PWM sinewave

Therefore I changed the CAPCOM-program on the HITEX-site into this:

#define _MAIN_

/* External Function Prototypes       */
/* We geven de nodige submappen mee	  */

#include <reg167.h>
#include <stdio.h>
#include <intmac.h>

//volatile int i;//test
/*** Main Program Loop ***/

sbit PWM0 = P2^0;
//
//prototypes
//
void main(void);
void init_controller(void);
void CAPCOM0_init_166(void);
void timer0_1_init_166(void);
void timer0_int(void);

int k;



//
//program
//
void main(void)
{



   init_controller() ;     	/* Set up controller and start drive */
   							/* We springen naar de hoofdmap Control.c, meer bepaald de functie init_controller()*/

   IEN = 1 ;                /* Global interrupt enable */

   while(1)
	{

	}
}

void init_controller(void)
{
	PWM0 = 1 ;    			/* Make sure PWM0 is off                          */
	CAPCOM0_init_166() ;    /* Set up CAPCOM0 in double register compare mode */
	timer0_1_init_166() ;   /* Set up timer 0  & 1 for timebases              */

}

void CAPCOM0_init_166(void) {

      /* Set up P2.0 & P2.4 as output compares */

      DP2 = 1 ;  // Set P2.0 to output
      P2 = 0 ;

      CCM0 |= 0x0005 ;    /* Compare mode 1 for PWM generation           */
                          /* CC0 uses timer 0                            */
      CCM2 |= 0x0004 ;    /* Compare mode 0 for double register mode     */
                          /* CC8 uses timer 0                            */

      CC0 = 0xFF00 ; /* Set initial duty ratio to 100% off */
      CC8 = 0xFF00 ;
      }


/*** Overflow Interrupt On Timer 0 To Define PWM Period ***/
void timer0_1_init_166(void) {

      /*  timer 0 = 200us PWM Period */

      T0IC = 0 ;
      T0REL = 0xFE00 ; /* Set reload value for 200us at .4us per count */
      T0    = T0REL  ; /* Make sure first synth interrupt is after    */
                       /* first controller interrupt                  */
                       /* The setting of CCx registers to zero         */
                       /* ensures that no unwanted outputs will occur */

      Set_Priority_11(T0IC) ;

      T0IR = 0     ;        /* Clear any spurious interrupts                 */
      T0IE = 1     ;        /* Enable timer overflow interrupt               */
      T0R = 1      ;        /* start  timer 0                                 */
} /* End init_timer_0*/


void timer0_int(void) interrupt 0x20  {

		IEN =0;
		k = 0x00BB;

		CC8 = 0xFF00+k;
   		CC0 = 0xFE00;

		IEN =1;
}

Problem: in the interrupt of the timer, I would like to change automatically the values of CC0 and CC8, by referring to a sine-table. But the µC doesn't seems to calculate another variable? Can someone help me out??

void timer0_int(void) interrupt 0x20  {

		IEN =0;
		k = 0x00BB;

		CC8 = 0xFF00+k;
   		CC0 = 0xFE00;
