That the system looks for in the 'current directory' first and for that it asks you the disk of the executable?

Thanks meynaf.

Yep, code mask out the bit unused in real DDF registers (like for FMODE).
So no 0000-00ff range :)
This made the proposed solutions much more interesting.


Exaggerated!

Wait, this is not the proper way.
FMODE lower two bits should always work, like the 'real' FMODE.

So a value = $8007 is valid and set 'fetch' or that which is =2.
