LCD problem

dear friends,

** I want to write to LCD **
I have got a board for 8051 of which P2.2 is connected to RS and P2.3 is connected to EN.RW is connected to GND. D7,D6,D5 & D4 are connected to P2.4-P2.7.

Now i tried writing to the LCD but since i m very beginner cannot know how to write in 4bit. What i am trying from last 2 days is the following code.

If anyonw can provide me his/her sample code for ref. it will be greate.

sbit RS = P2^2;
sbit EN = P2^3;

/* 1st init. seq.*/
RS=0;
EN=1;
P2=0x03;
EN=0;

/* 2nd init. seq.*/
RS=0;
EN=1;
P2=0x03;
EN=0;

/* inst. to clear screen
RS=0;
EN=1;
P2=0x01;
EN=0;

I know this is not correct, but i am trying and so i require u r guidance.
