What is the reference modification...

Answer / ts nithiyanandan

Reference modification is nothing but moving the part of
value of dataname to other dataname.

01 a pic 9(10).
01 b pic 9(10).

move a(4:5) to b.

i.e., moving from 4th byte to 9th byte to dataname b.
from 4th to 9th is length of 5 bytes.
