Very difficult to say cause I've tested so many versions. The version above gives me a: 

invalid control request: '\071'

I think this is a problem with the key as I get other error messages when I change the way to pass the key. So what interrests me is if the way I pass the key is OK or if the problem is somehow with the way I open the file (if I have to state something like "rb,recfm=VB" which leads to a dump if I try it that way). And the problem is: There is NO documentation in the internet. The only thing I found is: "noone has tested this till now".
