Re: [cc65] Apple2 Libraries - Current status of file io ?

Hi,

To be honest I don't think so. That would be like saying Pentium 3 support
goes only with Win9x/WinME and Pentium 4 support is tied to Win2k/WinXP.
That would match a lot of PCs out there but technically makes no sense -
does it?

- ProDOS can make use of more memory but needs more memory for itself.
Therefore it is more attractive to use it with machines with more memory.
- ProDOS knows about subdirectories. Therefore it is more attractive to use
it on machines with bigger disks.
- ...

But these things are more or less soft facts. The hard fact is that - as
mentioned - the assembly language interfaces of DOS 3.3 and ProDOS 8 are
totally different. This means that all existing assembly language program
will only run on one DOS or the other. This means that people are most of
the time not free to decide what they use but have to use what their
favorite programs are built against. In many cases this means using both
DOS's.
