Could of gotchas with dialogs in INIT code. First, you have to initialize
all of the managers, just like an application. This implies that you have
to allocate a block of storage for the quickdraw (and any other) global
variables. This would have to be 206 bytes (I think), plus any space for
your own global variables. Then you have to point A5 to the end of this space.
This is the tricky part, and might require some assembly code.

Finally, if you are planning on this code every running on an SE, you have
to clear out the global variable DeskHook. If this global variable is the
default -1, the machine will crash when the dialog is closed.

Good luck!
