Exercise Working In The Dialog Area; Changing Dialog Area Characteristics - Tektronix 4106 Operator's Manual

GETTING ACQUAINTED
EXERCISE 3: WORKING IN THE DIALOG AREA
In this exercise you will learn about the terminal's dialog area and how to get
information from the terminal about its settings.
Think of the terminal's screen as a piece of double-paned glass. On one pane the
terminal displays all dialog (that is, communication between you and the terminal ,
such as Setup commands, or between you and an applications program running on
a host computer) . This " front " pane is called the dialog area. (You used the dialog
area when you entered the FACTORY and STATUS commands earlier.) The pane
behind the dialog area contains the graphics and is called the graphics area. (You 'll
learn about this area in the next exercise .)
The purpose of the dialog area is to keep text that is not part of a graphics image
from obscuring the graphics.
CHANGING DIALOG AREA CHARACTERISTICS
You can change several characteristics of the dialog area. For instance one thing
you might want to do is make the dialog area invisible so you can see the graphics
behind it. Do that now.
Press the Dialog key at the top left of the keyboard .
The text you entered earlier is no longer displayed. If an image were in the graphics
area, you could see it without the text interfering .
Now, press the Dialog key again to make the dialog area visible .
You can also decrease or increase the number of lines displayed in the dialog area.
Look at the list displayed on the screen as a result of entering the STATUS
command earlier. It occupies a large part of the screen.
To change the size of the dialog area , enter the following commands :
DALIN ES 10
STATUS DIALOG
The first command reduces the number of lines displayed on the screen . The
second command gives you dialog area status just as it did before, but this time
you can see only ten lines on the screen .
