Hi Rick
How about a short tech help video on the topic
3.   Option Private Module

      The Option Private statement is less widely known. It is used at module level to indicate that the entire module is private.
      What does that actually mean in practice?

      With Option Private Module, module-level parts not declared Private are available to other modules in the project, but not to other projects or applications.

      This has another benefit in that it can be used to fully hide details of constants, variables and procedures in an ACCDE file.
      When an ACCDE file is created, the project is compiled to what is known as 'p-code' and the module code is no longer available to view or edit.

      Clicking on a code module in the VBE, will cause this message to be displayed

Thanks
