While running an application the user sometimes requires help. For example, the user may need assistance in making a choice, recalling the name of an application command or the use of a function key, or locating information.

Using IPF, you can develop a user interface that provides general help for application windows, and contextual help for fields within windows.

Implementing the IPF user interface when creating helps for an application requires two different development efforts:

• Developing the programming code that communicates with IPF and the Presentation Manager to display help windows.

• Developing a library of help information that IPF refers to in response to a user request.

This section will concentrate on the first development effort: writing the programming code that enables communication between IPF and the Presentation Manager.
