35 Console command execution and command text buffering.
37 Any number of commands can be added in a frame from several different
38 sources. Most commands come from either key bindings or console line input,
39 but entire text files can be execed.
41 Command execution takes a null terminated string, breaks it into tokens,
42 then searches for a command or variable that matches the first token.
