Using AT24c02 for random read operation

I had written a ASM code for Driving a EEPROM using P89V51RD2...........
It works fine for sequential write n read....
But the problem is, tat it doesnt read for random..... Plz hep me in tat...
I have placed my code.....

pre SDA equ P1.0 SCL equ P1.1

WRITE equ 10100000B READ equ 10100001B

ORG 0H

MOV SCON,#50H ; Configuration for Reception of Serial Port MOV TMOD,#20H MOV TH1,#-3 ; Set the Baud Rate 9600 SETB TR1

;Store a byte "data" in location "addr" in EEPROM

MOV 10H,#50H ; ADDR= "10H" DATA= "50H" MOV A,#WRITE CALL SENDS MOV A,10H CALL SEND MOV A,10H MOV R7,A CALL SEND CALL STOP MOV A,R7 CALL DISPLAY

;Read the data frm EEPROM

MOV A,#WRITE CALL SENDS MOV A,#10H CALL SEND ;MOV A,10H CALL READ1 ;CALL STOP MOV A,R7 CALL DISPLAY ;CALL DELAY
