Subject: CPM 3.0

Since I am new (very new) to cpm 3.0 aka cpm plus I wonder if any of you
with far more experience than I would recommend against using extended
directories.  Would this then make all my 2.2 disks including hard disk
compatible and useableby 3.0?  I don't see very much activity on this
subject and I wonder if there isno interest or if the compatibilty
problems aren't as severe as I imagine them to be.

The only two things that I am aware of (without hitting the books too
hard) is that direct calls to the bios are not supported by 3.0 and that
the directory can look different from 2.2 if so optioned.

I am beginning to have second thoughts about installing 3.0 for those
reasons and "primarily" because I have fallen in love with zcpr2.  Is
there a "real" advantage to 3.0 or not?
