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.
Bottom Status/Label Line Display
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 is displayed, such as if the screen is 44 lines and the
page length is 25 lines.
