BLOAD can be used within a BASIC program to load screens,
sprites, and other binary data. Execution continues with the state
ment following the BLOAD, unlike DLOAD or LOAD.
EXAMPLES:
BLOAD "SPRITES", BO, P3584
LOADS the binary file
"SPRITES" starting in
location 3584 (in BANK 0).
BLOAD "DATA1", DO, U8, B1, P4096 LOADS the binary file
"DATA 1" into location 4096
(BANK 1)from Drive 0,
unit 8.
—Load and execute a program which was saved as a binary file
BOOT "filename" [,Ddrive number][<ON | ,)Udevice]
The command loads an executable binary file and begins execution
at the predefined starting address. The default device number is 8
(drive 0).
EXAMPLE:
BOOT
BOOT "GRAPHICS 1",
D0, U9
BOOT a bootable disk (CP/M Plus for
example).
LOADS the binary program
"GRAPHICS 1" from unit 9, drive 0,
and executes it.

—Draw box at specified position on screen
BOX [color source], X1, Y1 [,[X2,Y2][,angle][,painty
where:
color source 0 = Background color
1 = Foreground color
2 = Multicolor 1
3 = Multicolor 2
x1, y1 Top left corner coordinate (seated)
x2, y2 Bottom right corner opposite x1, y1,
(scaled); default is the PC location.
angle Rotation in clockwise degrees;
default is 0 degrees
