[Coco] Extract BIN from DSK

[Bob Devries]

To see if a programme will properly execute at another address, it is only 
necessary to offset load it. If it crashes when you do that, it's a nogo.

LOADM"CALIXTO",&H100 : REM just a 256 byte offset here.
EXEC

That's all you really need, I think.
If it survives that, it should also work in a ROM location at, say, &HC000.
