What is usage pointer in cobol?..

Answer / sriram

Declare a pointer as an elementary data item bearing the
USAGE IS POINTER clause, with no PICTURE. E.g:
05 EXAMPLE-P USAGE IS POINTER.

EXAMPLE-P is a four-byte field which can store the address
of any data item. Unless you're interfacing COBOL to
Assembler or something, you really don't care what the
pointer looks like internally. It's just a piece of magic
which enables you to access the thing it's pointing to.
