Program function (PF) key definitions

A set of program function (PF) key definitions is maintained for each MainView product family and the General Services LOG application. These definitions make PF key usage unique to each product.


PF keys are also referred to as function keys or F keys.

The key definitions are maintained as members of a site or a user's BBPROF data set. The member name is xxxx PFK, where xxxx can be any of the following values:

  • CICS, DB2, AO, or IMS for the product applications

  • BBI for PF key defaults if no product application PF key members exist

  • LOG for log display defaults

The following table describes the default PF key definitions.
