Global Variables

The packages publish what they know and read what the machine publishes, and these lists are where the two meet. Almost all of them arrive with a module rather than with a plain library, so a project without that module declares none of its lists. Which of them your code writes and which it only reads is on What Your Code Owns.

A member a package keeps in its retain store is a commissioned value, set on the machine itself. An assignment to one from your own code is refused at build, naming the list, the member and the package it belongs to: writing it in code would put the commissioned value back to that number on every start.
