lcd not working

hi
i am trying to interface an 16x2 lcd onto an arm7 board lpc2148. the pins i am using for the data is p0.16-p0.23
and for control signals ie rs rw e i am using p1.24 p1.25 p1.26 respectively.When i dump the following code nothing is getting changed in the display .can anybody help me out...i am attaching the code here ..kindly do the needful

#include<LPC214x.h>
void init_PLL(void);
void init_GPIO(void);
void lcd_data(unsigned char);
void lcd_cmd(unsigned char);
void lcd_init(void);
void delay(unsigned int);

#define RW 0x02000000
#define RS 0x01000000

int main(void)
{
        init_PLL();
        init_GPIO();
        lcd_init();
        while(1)
        {
                lcd_data('A');
                lcd_data('B');
                lcd_data(96);
                lcd_data('d');
                delay(0xffffff);
        }
}

        PLL0FEED=0x00000055;
         while(!(PLL0STAT & 0x00000400)); // CHECK WHETHRT THE CCLK IS GENERATED EXAXT VALUE
