hi explanation for refrence modification(begin:(length))
ref modification defines a data item by specifying its leftmostcharacter and optionally a length
e.g
working-storage section.
77 a pic x(10) value 'abcdefghij'
77 b pic x(5).
77 c pic x(9).
procedure division.
move a (1:4) to b
move a (1: ) to c
display c
diplay b
...............................................then the result will be
b=abcd
c=abcdefghi
i hope i made ur concepts clear
