Answer Posted / prasanna
1. RENAMES just renames the variable whereas REDEFINES can
give a new definition to a variable and can also rename it.
No one is using RENAMES claus e nowadays..
2. COMP is numeric data represented in Binary, number must
be a positive integer. bytes vary from 2 to 8 depending on
th e PIC clause. COMP-3 is variable declared in packed
decimal form. Each digit will take half a bit of storage.
sign is stored seperately regardless of S specified
3. Will create a dummy dataset.
4. In COBOL the variable declaration is restricted to 30
and so, it 'll result in an error. For theory sake, one can
use REDEFINE clause.
5. Variables are declared in SECTION and are used in
PARAGRAPHS..
