Standard Presentation Space Sizes

When specifying a location within a presentation space, Viewer API methods use column and row coordinates to specify the cursor position.

The following sections provide the standard presentation space sizes for 3270, 5250, and VT sessions.

The sizes shown in the following tables are called configured sizes, and represent the largest possible presentation space sizes for each terminal. Host applications can specify a subset of the presentation space to use. When this happens, the result is the current size. The current size is always less than or equal to the configured size. The Viewer API can work with either configured sizes or current sizes.

The row totals shown in the following tables do not include the operator information area (OIA), also known as the status line. The OIA appears at the bottom of each screen and contains information about the session status (such as what mode the screen is in) and other information (such as the location of the cursor).
