Atari 400 User Manual page 57

Press the RETURN key twice to put two more
empty lines on the screen. This is like using the
RETURN on a typewriter to putspace between
lines of text.
SCREEN 6
Now that you have pressed RETURN many
times, the cursor is getting closer to the bottom
of the screen. We have seen that the cursor will
wrap around horizontally. Will it wrap around
vertically, too 7 Keep pressing the RETURN key
to make the cursor move to the bottom of the
screen.
SCREEN 7
When the cursor reaches the last line, press RE-
TURN again. Instead of the cursor moving, the
whole screen moves! The cursor stays at the bot-
tom, and the whole screen moves up. The top
line gets shoved off the screen and cannot be
retrieved .
If you press RETURN enough times, you will get
rid of all the lines on the screen. Moving all the
lines up off the screen in this manner is called
scrolling.
SCREEN 8
When you have a BASIC cartridge (or any other
programming language) in your Atari, the RE-
TURN key has another function. This function is
described in the next exercise, "RETURN KEY:
BASIC."
