Hi Willi, > Here you go: first of all thanks :-) >Version Contents >------- -------- >1.0.1 7 >1.0.2 7 >1.1.1 7 >1.2 2 Is there some misunderstanding or transmission error? It looks like you wrote, that the first three verions had a KVERSION of _SEVEN_ ! I've got a 1.0.1 here that has zero and I've got a very early Global Page Disassembly Listing showing zero as well...

That >makes much more sense. Indeed ;-)) So for the records the reason I asked for that: I need to implement an 'operating system ID', but I can't use the KVERSIONs straight because I need the $00 as "No ProDOS present at all -> DOS 3.3 active". But from what I learned now I can safely add a $10 to all values < $10 because there were never KVERSIONs in the range $10-$1F. This approach gives me both a destinctable $00 and the benefit of the high nibble of my ID being always identical to the ProDOS major number :-)) Again thanks for your help, Oliver
