here is program of lcd interfacing with 89c51,,,,,,

//Program to test LCD. Display single character "A"

#include<reg51.h>
#define cmdport P3
#define dataport P2
#define q 100
sbit rs = cmdport^0; //register select pin
sbit rw = cmdport^1; // read write pin
sbit e = cmdport^6; //enable pin

void delay(unsigned int msec) // Function to provide time delay in msec.
{
int i,j ;
for(i=0;i<msec;i++)
for(j=0;j<1275;j++);
}

void lcdcmd(unsigned char item) //Function to send command to LCD
{
dataport = item;
rs= 0;
rw=0;
e=1;
delay(1);
e=0;
}

void lcddata(unsigned char item) //Function to send data to LCD
{
dataport = item;
rs= 1;
rw=0;
e=1;
delay(1);
e=0;
}

void main()
{
lcdcmd(0x38); // for using 8-bit 2 row mode of LCD
delay(100);
lcdcmd(0x0E); // turn display ON for cursor blinking
delay(100);
lcdcmd(0x01); //clear screen
delay(100);
lcdcmd(0x06); //display ON
delay(100);
lcdcmd(0x86); // bring cursor to position 6 of line 1
delay(100);
lcddata('A');
}

i picked the programme from here it is also not working and showing syntax error in last 4 to five lines,,,
