That's the scenario, I'm refering to. Does somebody know for sure?

Does the cc65 POSIX file I/O library use sequential files or relative files?

Is it correct to say that the maximum number of open files depends on
the maximum number of "channels" supported by the actual device ? So
this number would be something being stated in the specs or even used
in advertisements ?

So I presume there's no "well known" low level entry point to the
routine being called if the current active file handle turns out to be
the screen (?)

Again thanks, Oliver
