Murali,


Comp-4 is nothing but an equivalent of BINARY.It occupies the same storage as that of a comp item. Comp-5 data items are represented in storage as binary data. The data items can contain values up to the capacity of the native binary representation (2, 4 or 8 bytes), rather than being limited to the value implied by the number of nines in the picture for the item (as is the case for USAGE BINARY data). When numeric data is moved or stored into a COMP-5 item, truncation occurs at the binary field size, rather than at the COBOL picture size limit. When a COMP-5 item is referenced, the full binary field size is used in the operation.

Comp-6 items are not applicable to mainframe cobol

Hope this helps...

Cheers
