Flash Player 8 supports only AVM1 bytecode (compiled from Actionscript
1.0 and 2.0 - and haXe).
Flash Player 9+ supports AVM1 and AVM2. Actionscript 3.0 gets compile
into AVM2 bytecode (and haXe).
There is no way to use Actionscript 3.0 with Flash Player 8 and lower.
Even if you use haXe, the display list API is different when targeting
Flash 9+ vs. Flash 8- so even haXe isn't completely compatible.
On alternative platforms - AS3 (AVM2) is available on more platforms
than it used to be, even being supported in some versions of Flash Lite,
but AS2/AS1 (AVM1) is still more compatible (especially with older
hardware/platforms).

Hi all,
I am searching informations about using Actionscript 3 for projects,
which have to run in old, old Flash Versions. I need arguments for
customers who still work with Actionscript 2.
Any suggestions are welcome, will do a paper on this issue.
Thanks in advance
