Although the Flex command-line compiler (mxmlc) can compile MXML+ActionScript files into SWFs, I need specific insights into its capabilities, via the command-line switches.
- Configure which language you’re writing in, ActionScript 2 / 3
- Configure which Flash Player version you’re targetting, 7 / 8 / 9 / 10
- Configure what frames of the movie, contain what ActionScript code.
You can’t define the language afaik – mxmlc version 3 is an actionscript 3 compiler only. There may be some backwards compatibility, but it’s not a combined AS2 and 3 compiler.
I’m not even sure what your third point actually means, or in fact what you’re asking overall.
