Screen Display and Pages

This terminal offers a variety of screen lengths including 26, 30, 44, or 52

lines. These numbers include the top and bottom status lines (or label line),

as well as the lines used to display data. A "page" of terminal memory

represents the total number of lines that can be accessed, whether or not

they are all viewable on the screen at once. Refer to Appendix A for the

number and lengths of pages available for your setup.

The page length is comprised of a base page length multiplied by 1,2,4, or 8.

For instance, in certain modes, 24 (24x1), 48 (24x2), and 96 (24x4) are

available, the same way that 25(25x1), 50 (25x2), and 100 (25x4) are. The

base page length and the screen size determine whether a bottom status

line or label line is displayed or not.

With a screen length of "26 lines," the page lengths that are multiples of 24

allow the bottom status/label line to be displayed, while those that are

multiples of 25 do not. The same idea applies with the 44 line screen size.

A page length with 42 lines as a base page size will display a label line,

while the 43 line base page length will not. An exception to this rule is if the

screen length is significantly larger than the that page size, then the label

line will be displayed, such as if the screen is 44 lines and the page length is

25 lines.

Up to three viewports can be selected on a page. Each viewport has

its own character attribute, cursor position, field attribute propagation, tab

stops and scrolling region. All of the viewports are displayed on the same

screen and can be partitioned with a visual separator line. If the keyboard

is associated with one viewport and the host is associated with another, it is

possible to receive data in two viewports simultaniously.
