    I was successfully able to erase the program memory and again write into the program memory using IAP.However in 89V51RD erasing program memory takes place sector wise(i.e 0x7F bytes at a time) but my address location unfortunately does not start with multiple of 0x7F .Hence I am mot able to program some bytes.So i wish to relocate entire address of the variables according to my need .I hope you understand my situation ,PLEASE HELP
