SCNCLR
The SCALE command affects the sprite coordinates in the MOVSPR
command. If you add scaling to a program that contains sprites,
adjust the MOVSPR coordinates accordingly.
NOTE: The functions which return the location of the pixel, cursor,
SPRITES, etc. do not return scaled coordinates—See RDOT,
RSPRITE.
—Clear screen
SCNCLR [mode number]
The modes are as follows:
Mode Number
0
1
2
3
4
5
Mode
40 column (VIC) text
bit map
split screen bit map
multicolor bit map
split screen multicolor bit map
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) split screen multicolor bit map.
SCRATCH
—Delete a file from the disk directory
SCRATCH "filename" [,Ddrive number]
[<ON | ,>Udevice number]
This command deletes a file from the disk directory. As a precaution,
the system asks "ARE YOU SURE?" (in direct mode only) before the
Commodore 128 completes the operation. Type a Y to perform the
SCRATCH or press any other key to cancel the operation. Use this
command to erase unwanted files, and to create more space on the
disk. The filename may contain template, or wildcards (?,* etc.). The
default drive number is 0 and default device number is 8.
EXAMPLE:
SCRATCH "MY BACK"
This erases the file MY BACK from the disk in drive 0.
