Is ActionScript a procedural language? It has class declarations and object usage, and so is it not a OO language?

Being procedural and OO are not mutually exclusive. Procedural languages are defined, in part, as languages in which the programmer develops an order of flow. ActionScript, which supports many OO principals, and true OO languages such as Java, fit this description.
