No!  Never ever call DeskStartup under ProDOS 8 (even though AppleWorks 2.0
does; they fixed that in AppleWorks 2.1).

DeskStartup tells NDAs that an application which fully supports NDAs (not CDAs!)
is starting up, and that a whole bunch of toolsets are available and already
started up.

Well-behaved NDAs are perfectly welcome to crash your system for you if
DeskStartup is called under ProDOS 8.

The problem with *loading* CDAs under ProDOS 8 is that the Loader isn't around
to interpret the object module format that the CDAs are stored in.  That's
what P8CDA (see my recent msg) does.

   My opinions are my own, not Apple's.
