Chapter - Global variables
The current child loop is an input-loop variable.
The delegate event handling to parent loop is a truth state variable.
The line event pending is a truth state variable.
The current input loop is an input-loop variable.[This should only be used with the special input loop rulebooks, and carefully even then.]
The current loop context is a loop-primacy variable.[This is set immediately before the input loop event-handling rules are called, so that they can accurately refer to the context. This is to be recommended over using the "current input loop" + "loop context"]
