Screen Format
The IBM Personal Computer Display has 25 lines of 80
characters each. Once you have established a local VM/PC
session or a remote 3277 session, the first 24 lines will look
exactly like a 3277 display screen.
The 23rd and 24th lines are the place on the screen where
you enter commands which allow you to tell the computer
what you want it to do. This place is called the input area.
The kinds of commands you may use are described in
Chapters 5 thru 7. The 24th line looks like this:

The end of the 24th line is reserved for screen scroll
commands and status notices.

the scroll area. When you press ENTER, both commands
will be executed.

The Screen Scroll facility allows you to look at data which
was on your screen but has been erased. All transactions to

scrolled off the display by the CLEAR key, PA2 key, or the
Diagnose 58 erase option, it is not lost but placed in the
terminal history buffer.
The history buffer may be viewed any time the Local 3277
Session is active. The screen scroll commands are entered in
the Scroll: area at the end of the 24th line. The screen scroll
commands are:
