<B>CLS Clear Screen</B>
|
|
|
|
<B>CLS</B> [0 | 1 | 2]
|
|
|
|
Clears the screen, as described below, and returns the cursor to the
|
|
Home position (row 1, column 1).
|
|
|
|
0 CLS 0 clears all text and graphics.
|
|
|
|
1 CLS 1 clears just the graphics viewport, if a VIEW
|
|
statement has been issued. If no VIEW statement has been
|
|
issued, CLS 1 clears the entire screen.
|
|
|
|
2 CLS 2 clears just the text window. The bottom screen line
|
|
(line 25 or line 43) is left unchanged.
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
<B>Notes:</B> CLS with no argument clears the entire screen, unless a
|
|
VIEW statement has been used to create a viewport in
|
|
graphics mode--in which case CLS clears only the current
|
|
viewport.
|
|
|
|
CLS resets the "last point referenced" (LPR) so that the
|
|
next graphics command that uses the STEP option references
|
|
the center of the screen.
|
|
|
|
In text mode, CLS clears the active page to the background
|
|
color. In graphics mode, CLS clears the entire screen
|
|
buffer to the background color.
|
|
|
|
Other ways to clear the screen include SCREEN, WIDTH, and
|
|
Ctrl-Home.
