that said, a *working* lseek isnt hard (skip forward by reading until desired 
position, skip backwards by reopening the file and seeking forward) is not the 
problem - "only" an efficient one is :)

here: is the one i am currently using, 
it still needs a bit of rework perhaps to work in the lib under all conditions 
(notice that i only ever tested it with my "os" kernel, not the regular cc65 
runtime) :)

no idea. looks easy enough to implement though (a first version could be 
knocked up in C by using cbm_ drive functions)
