Mainframe Express Host Compatibility Option (HCO) is a set of tools that enable you to offload DB2/MVS and DB2/VM development and testing to a PC using some of IBM's family of DB2 Universal Database products. Host Compatibility Option can also be used with some older IBM relational products such as DB2 Common Server V2.1.
Mainframe Express Host Compatibility Option does this by allowing EBCDIC-enabled programs to work with DB2 UDB. This means that you can use Mainframe Express IMS Option and CICS Options with DB2 UDB while the data is still stored in ANSI format.
