NetLinx Modules
The ability to reuse code is a desirable goal in software development; however, code reuse takes careful planning and organization. NetLinx provides tools such as functions and modules to promote reusability.
Modules are NetLinx sub-programs designed to be "plugged into" a main program.
Technically, modules can contain declarations to other modules, provided that no circular references are involved. However, because different instances of the same module must not be separated by instances of a different module, it is highly recommended that you do not declare modules from within other modules if you have multiple declarations of the parent module they will then be separated by the declarations of the child module.
When using modules, always keep the order of usage in mind. The modules must be placed (in the program code) in the order in which you want them to occur.
