Gee, you only use one DA at a time?  I often use several.

Anyway, the system just InitialLoad-s all the DAs.  This doesn't necessarily
mean that all of their code is in memory (as Scott Lindsey already pointed
out).  The DAs are free to use dynamic segments so that parts (perhaps almost
all) their code stays on disk until it's actually needed.

Note that CDAs that need to work under ProDOS 8 don't have the option of using
dynamic segments (the Loader isn't present while ProDOS 8 is active).

   My opinions are my own, not Apple's.
