A window is an area of the screen with visible boundaries within which information is displayed. Often a single window uses the entire screen for its information. Because online information is best presented in small pieces, or units, most designs call for a multiple window format. This chapter explains how to size and position more than one window on a screen, and how to use attributes that enable IPF to open and close those windows. Before you begin this chapter, make sure you read about the OS/2 standard windows described in IPF User Interface.

For a summary of attributes described in this chapter, see Summary Tables of Attribute Values for Origin and Size, Summary Table for Heading Attributes, and Summary Table for Link Attributes.
