Clear screen
SCNCLR[mode number]
The modes are as follows:
Mode Number
Mode
0
40 column (VIC) text
1
bit map*
2
split screen bit map*
3
multicolor bit map*
4
split screen multicolor
bit map*
5
80 column (8563) text
This statement with no argument clears the graphic screen, if it is
present otherwise the current text screen is cleared.**
EXAMPLES:
SCNCLR 5 Clears 80 column text screen
SCNCLR 1 Clears the (VIC) bit map screen
SCNCLR 4 Clears the (VIC) multicolor bit map split screen
NOTE: * The bit map area is the same for both hi-res and
multicolor, the different mode numbers select other parameters to
clear e.g. 40 column text (2 and 4) color ram (3 and 4).
** If a graphics screen has been created but is not selected
(GRAPHICS =0) it will not be cleared. If you are using 2 screens
(80 columns for text and 40 columns for graphics) SCNCLR will
clear both text and graphics screens if called from the 80 column
screen.
