==== Flash utility usage ====
|FLASH,"filename",slot
Where filename is a file from CPC disc, slot is a number from 0 to 6.
Slot 0 is the BASIC slot enabled with the ''boot'' DIP switch.
The rest of slots are enabled with the ''enable'' DIP switch.
|FLASHLOW,"filename",slot
Same than |FLASH command but for lower ROM replacement. It's also enabled with the ''boot'' DIP switch.
'''Important''': In both commands, an empty filename means to clear the slot.
|LIST
This command lists the current slot assignments for both lower and upper ROMs.
'''Important''': After running any of the commands all the slots will be disabled until a power down is performed.
