hi zobi,

use DPTR register of 8051..

or take an unsigned int what would be a 16 bit variable;

eg:

 

unsigned int i=0x1234;

P1=i;

P2=i>>8;

 

The output for P1 will be 0x34 and for P2=0x12;

 

i tried the above example you can use according to your program

i have tried to use DPTr but it is not possible DPTR can not be used for data storage or for saving any value

 

and the e.g. you have given is so difrrent , i cant understand what does it mean is it in ASSEMBLY or C LANGUAGE?
