Format: BEEP [number]
BEEP
Defaults: number = 1
BEEP outputs the specified number of 'beeps' (max 255) from the Dragon.
Format: BOOT [drive]
BOOT
Defaults: drive = DEFD
BOOT loads sectors 3 to 18 of track 0 of the disk in the specified drive into memory from
9728 onwards; sets DEFD to 'drive' and executes the program from address
9730. The first two bytes of sector 3 must be OS.
NOTE: The BOOT command is primarily used to load another operating system (eg.
OS9). Use on a network station will crash the machine since such operating
systems require direct access of the disk system. The command should only be
used for loading programs which remain in the BASIC enviroment eg. auto
BASIC loaders.
