#include <mcs51/8051.h>

 #define port2 = P2
 #define rs = P1_0
 #define rw = P1_1
 #define e = P1_2
// __sbit __at (0x90h)rs;            //  sbit rs=P1^0;
// __sbit __at (0x91h)rw;            //    sbit rw=P1^1;
// __sbit __at (0x92h)en;              // sbit en=P1^2;

void lcmd ( unsigned char);
void lcdat (unsigned char);
void delay();
void main();


  P2 = 0x00 ;                    // P2=0x00h;
    while (1)
    {
        lcdcmd (0x38);
        delay ();
        lcdcmd (0x01);
        delay ();
        lcdcmd (0x10);
        delay ();
        lcdcmd (0x0c);
        delay ();
        lcddat ('W');
        delay ();
        lcddat ('A');
        delay ();
        lcddat ('J');
        delay ();
    }
}
 void lcdcmd (unsigned char val)
 {
   P2=val;
   rs=0;
   rw=0;
   en=1;
   delay ();
   en=0;
 }
 void lcddat (unsigned char val)
 {
     P2=val;
     rs=1;
     rw=0;
     en=1;
     delay ();
     en=0;

 void delay ()
 {
     unsigned int i;
     for (i=0;i<1200;i++);
 }

Regarding the formatting, you might want to read the markdown syntax guide. I took the liberty to edit the post for you.

Your #define syntax looks wrong. You have to write #define new_name old_name.
