Combined command shells/program launchers (like Davex) could *sort
of* be written for DOS 3.3, but it just wouldn't be the same!  Under
ProDOS there is an established "quit" convention that allows the
launching program to regain control from any program that quits the
right way.   There is no such thing under DOS 3.3.  The machine
language inteface to DOS 3.3 is harder to work with, and the lack of
a hierarchical directory structure is a real drawback.  (Anyone who
thinks subdirectories are a PAIN has *never* used Davex...they've
probably just used AppleWorks, which makes directories about 256
times harder to use than they should be.)
