One term that you've already seen is modules . From the pictures in the previous chapter you saw that the Visual Basic IDE can have many modules. But what exactly are they? A module is really just a place to store procedures.
We generally group procedures into logical units. So, if we created a set of string handling procedures, we could put them all together in a single module, and call the module String Handling. As you go through the book you'll see this in practice. Each chapter has its own code module where the code for the chapter goes. This makes it easy to find.
