Linkage Symbols are used at run-time by actionscript, they are like actors awaiting in the backstage, ready to let the show go on at your call. The movie created by this sample in effect will looks empty an unusable as is.

The main objective of creating movies with linkage symbols is to constitute the initial stage developing a whole flash app. Mk support actionscript partially at bytecode level with an approach very similar to flasm, see sample #18, you may use advanced open source developing tools such are:

• eclipse - the main development environment
• asdt - eclipse plug-in: actionscript development tool
• as2ant - eclipse plug-in: ant task to automate swf production/compilation
• mtasc - a powerful actionscript 2 compiler

The are useful video tutorial to get start in developing in flash, mk "can" be used instead of flash IDE e.g. in the video #07
