yes, I read those parts of the manual - but to be hoenst,
I dont fully understand it. I understand, that I have to
define a filetype (in my case that would be like this:
:filetype·
        suffix in myin
        suffix out myout

# this says: everything ending with ".in" is of the type "myin"
# and files ending ".out" are of the type "myout".
)

But my question is: how could I tell aap, that to do, when aap
should make an x.out of an x.in.

I assume, that this is very simple.

        any suggestion is welcome
        Joerg
