VIEW PRINT
Statement
VIEW PRINT top line 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.
