Thanks alot for taking the time.
I get it now. I sort of, but not fully, misunderstood the conecpt of binary files. 
The thing I was after; and the thing Im playing with now after a more succesfull time with google, 
is writing more specific things to a file than just strings.
English is not my native language so please forgive me, but
I wanted to write specifc 16bit codes, and read them. And later play with bitwise operations on them. Sort of.
It might not make sense at all, but hey..  it doesnt have to.
Thanks anyway. :)
