	  How does the Finder launch programs ?  Who allocates the A5
	  world memory, the finder ?  How do global variables get
	  initialized under Think C, MPW ?  What kind of code do these
	  compilers insert in the application, which runs before
	  main() ?

          Lots of questions, I know.  If I understand right, Think C
	  places all the global data in a resource of type DATA, and
	  inserts some code which runs on startup to read that info
	  into A5 world.  But, does the application have to allocate
	  its own A5 world and then set A5 to point somewhere in it ?
          MPW has its %A5init thing - does that work similarly ?

	  Just curious...
