startUp messaging hierarchy

[FlexibleLearning.com]

I find myself unable to answer this rather basic question, and cannot locate
any information...

e.g.
This is both incomplete and also most likely incorrect...

startUp (if engine is not already loaded)
- frontScript:
-- PreOpenStack
-- PreOpenCard
-- openStack
-- openCard
-- preOpenBackGround
-- openBackground

preOpenStack
preOpenCard
openStack
openCard
preOpenBackground (if closed)
openBackground (if closed)

- backscript:
-- PreOpenStack
-- PreOpenCard
-- openStack
-- openCard
-- preOpenBackGround
-- openBackground

Anyone?
