Just found a nice surprise: I kept the vectors starting from $FF81 and 
all routines connected to them. The BASIC command OPEN starts at $E1B1, 
collects some info from BASIC and executes the "open a file" at $FFC0. 
The same happens with the BASIC command CLOSE. So I only have to provide 
the name and some numbers and I'm ready to go.

The Kernal reserved ten bytes for a "logical file table". I simply 
reserve one entry permanently for checking if files exist (or what ever) 
so I don't have to spend time and code on finding out if I can reserve 
an entry for "my" needs.
