ASnative

In general, ASnative (i, j) returns a function reference. It’s like all the Flash functions are stored in a spreadsheet, and you can access them by rows and columns with ASnative. A convenient way to work with ASnative functions is to assign the result to a variable, and then execute the variable as a function.

The following list is pulled from the old flashcoders wiki, theres some annotations for various parts that could probably be added in here. You can visit the web archive to see the old page
