Display Menu (F3)
Page Length:
24, 25, 42, 43, 48, 50, 84, 86, 96, 100, (168), (172), (192), (200), *24, *25, *42, *43
Choose the number of lines per page. As many as ten pages (0-9) may be available, but the number of pages in memory depends on the number of lines per page,
the type of emulation, and whether 80-Only is selected for columns. The total lines used (Lines/Page times Number of Pages) cannot exceed 240. See the Page
Configurations in Appendix A (page 40).
Page lengths that are multiples of 24 or 25 and those that are multiples of 42 or 43 are displayed by default on a 26-line or 44-line screen, respectively. The extra
one or two lines on the screen can be used as status lines.
The selections shown in parentheses( ) are not available in dual session mode. If you choosse a page length preceded by an asterisk (*24, *25, *42, or *43), the
total number of pages will be two, where the first page contains the number of lines in the selection (24,25,42, or 43) and the second page contains the remaining
allowable lines. (See the Appendix, on page 37.)
Screen Length:
26 Lines, 30 Lines, 44 Lines, 52 Lines
Select the number of lines that can be displayed on the screen at one time. The page length affects the default screen length.
Screen Video:
Normal, Reverse
Choose between bright characters on a dark background (normal) and dark characters on a bright background (reverse). In reverse video mode only, the
Enhanced Attributes parameter is available (see page 3-8).
Display Cursor:
On, Off
Choose whether the cursor will be displayed.
Cursor:
Blink Block, Steady Block, Blink Line, Steady Line
Choose the appearance of the cursor.
Auto Adjust Cursor:
On, Off
Choose whether the screen attempts to follow the cursor down the page by scrolling just enough to keep the cursor in view.
Columns:
80, 132, 80-Only
Choose the number of columns that the screen can display. 80-Only provides more pages in memory for a given page length by disallowing changes to 132-
column display.
Width Change Clear:
On, Off
Choose whether the screen is to be cleared when the number of columns on the screen is changed from 80 to 132 or vice versa.
Note:
Changing columns from/to 80-only forces the screen to clear independent of Width Change Clear.
Speed:
Fast, Normal
Choosing “fast” improves the speed at which screen display occurs at the expense of minor, temporary distortion of text called “tearing.”
Scroll:
Jump, Smooth
Choose whether the data on the screen scrolls smoothly or “jumps” to accommodate data at the rate it is received.
Scroll Speed:
Smooth 1, Smooth 2, Smooth 4, Smooth 8
Select the number of scan lines per second the page scrolls up when smooth scroll is selected. Smooth 1 is the slowest rate and Smooth 8 is the fastest rate.
Refresh Rate:
60 Hz, 71 Hz, 82 Hz, 100 Hz
Choose the rate (number of times per second) at which the image on your terminal’s display is updated. This selection is only available in 26 or 30 line display
mode.
Overscan Borders:
On, Off
Choose whether the overscan borders are active. The borders extend video from one edge of the screen to the next. (To see the borders, select reverse for
Screen Video.)
