[Gnash-dev] Questions on actions and assets

[Jon Steinhart]

Part of the flash virtual machine is the data stack used by the swfs of
the latter day versions.  Also the current execution context in which
variables are stored, etc.  When is this stuff initialized?  Per flash
movie, per action script, per frame?

It appears that actions saved up and executed as when a ShowFrame is hit.
What is the ordering of work on a ShowFrame?  Are all of the actions
executed before drawing the display list or some other ordering?

What is the range of the action script program counter?  If a script
calls another, is there a separate program counter per script, a stack
of program counters, one per instance, or is the whole thing treated
linearly?

What is the lifetime of characters exported via ExportAssets?  Forever?
This would work in a web plugin that goes away occasionally but not real
well in a standalone device where the player never goes away.

Hope that these questions aren't too stupid.  Thanks,
        Jon
