Explicit actions stored in memory as literals.

• §1. Runtime representation

§1. Runtime representation. Literal version numbers arise from source text such as:

    let V be v2.31.1;

This is called only from the actions feature; in Basic Inform no stored actions exist, so if the function is called then an internal error will be thrown.

Version numbers are stored in small blocks, always of size 3. There are no long blocks.

                        small block:
    V ----------------> major version
                        minor version
                        patch version

See Architecture32Kit for more.

The default is "v0.0.0":
