Theres some great alternatives.
You can check out flex 4 beta free from
http://labs.adobe.com
The flex framework is free and allows u to code in actionscript 3 as well as mxml.
You can use any editor u like and compile your app via commandline or using a ide like eclipse for free.
theres also SE|PY or FlashDevelop.
If your looking for flash to make animations than u can try swish althought its not free. But, if your looking to code and make some real apps. There are plenty of free alternatives.
If you got any questions hit me up.I'll be glad to try and help.
Coding is good~ All the time!
