- Hmmm, maybe we're not talking about the same compiler. What I have was
- sold by Misosys as Misosys-C, but the manual called it 'something'-MC.
- There is no editor in the package...

- I have that one. Complete. Indeed at 0005H there is a hook for CP/M system
- calls, but don't forget that CP/M progs load at 100H, while the low-mem
- area is definately LS-DOS. Anyway, I think that swapping in a bank at the
- low-mem area should be possible.
- The only thing I'm really worried about is the allocation vector thingy.
- And the Disk-Parameter-Header. How many programs misuse those?
- Maybe it's better to strat by disabling all BIOS disk-related calls just
- to keep things safe, and see how far you get.
