Here again, we may wish to store all of

Here again, we may wish to store all of our code in the form modules, with each module containing the code needed for its form to operate properly. However, it's not uncommon for identical procedures to be used in more than one form. When that's the case, it's more efficient to store a single procedure in a standard module, for use by each of the forms that need it. The same is true for variable declarations. If a variable is used in a single form, it should be declared in the form module. But if it's used in multiple forms, it should be declared in the standard module. Proper use of code modules allows us to write code that runs faster and uses memory more efficiently.
