Meta Instructions - What are they?

Have you ever wondered what those funny looking instructions starting with ++ in Action diagrams are?

The following pages explain all about meta instructions and how to use them.

It starts off with some fairly simple examples and will progress to advanced uses of meta code, particularly in the context of building abstract class library objects.

Note: The content is based on the current release of Obsydian (V2.20). In some places enhancements have been included that will be available in a future release and the symbol is used to indicate this.
