RETURN
The
RETURN
key
is
much like the carriage return key on a typewriter.
It
causes the cursor (the flashing square
that
indicates where
the
next
character will appear) to return to the left-hand margin
of
the next line.
The
RETURN
key
is
also used to enter instructions in BASIC. After
keying in a line
of
your program, you press
RETURN
to enter that line into
memory.
A
RETURN
executed while the cursor
is
on
the bottom line of the screen
will cause the entire screen to scroll up, moving the cursor to the beginning
of the new blank line generated by the scroll.
