Viewing the Input Screen
When you start terminal emulation, you see all or part of an input screen on
the JANUS TE display. This section describes how you access other parts of the
input screen when you are not operating in Full Screen mode and how to enter
data into input fields.
The JANUS TE 16 x 20 display shows only part of each 25 x 80 screen that
appears on a full-sized terminal. You can use the JANUS TE display to access
the full screen by using the viewport movement functions described on the
following pages. This guide uses the following terms to describe the TE
display.
Screen Refers to a full 25 x 80 screen that appears on a standard terminal
display.
Viewport Refers to the 16 x 20 JANUS TE display. The viewport shows only a
portion of the 25 x 80 screen and you can move it around to show different
areas of the standard terminal display.
Note:
There are several display exceptions for non-EBCDIC keypad characters when
you are working in Terminal Emulation mode. Brackets [ ](
>)
and
> *
)
appear as parentheses ( ). You cannot use the ^ character (
O
) in TE mode.
How the Viewport Works
The viewport lets you view screens and enter data by showing the part of the
screen you are using. When you need to access part of a screen that does not
appear on the viewport, the viewport changes its display to show the part of
the screen you need. The viewport acts as a window to the larger screen, and
when it changes its display, it behaves as if it were “moving” across the screen.
Viewport movement functions are useful for viewing text that is outside of the
viewport boundary or for viewing error regions on the TE display. Refer to
your JANUS user’s manual for a detailed explanation of viewport movement
functions.
Note:
When you are using TE, the viewport automatically moves to the cursor when
there is data entry from the host or the terminal.
