Allowcation of more than one data items in a single memory
location.

01 b redefines a pic x(7).

Rules for Redefines

1. Should be different datatype and size
2. Redefined item should not contain value clause
3. Redefing item cantain redefined item
4. Redefines can't write in 66 and 88 level numbers
