TO
bottom
line
Creates
a
text viewport that redefines the text screen parame-
ters. All statements and functions that normally function within
the text viewport now function in the new text screen parame-
ters. Cursor movement and scrolling are also limited to the text
viewport.
Top line
specifies the
first
line of the text viewport.
It
may be in
in the range
1
to
24,
but must be less than
bottom line.
If you
omit
top
line,
BASIC assumes Line
1
as
the beginning of the
text viewport.
Bottom line
specifies the
last
line of the text viewport.
It
may be
in the range
1
to
24,
but must be greater than
top line.
If you
omit
bottom
line,
BASIC assumes Line
24
as the end
of
the text
viewport.
If you omit all parameters,
VIEW
PRINT defines the entire
screen
as
the text viewport.
Example
VIEW
PRINT
1
TO
15
BASIC defines the
first
15

All cursor movements, scrolling, and text screen functions and
statements are limited to these boundaries.
