Bug Extermination Techniques
IN THIS CHAPTER
Defining a bug and knowing why you should squash it
Recognizing types of program bugs you may encounter
Using techniques for debugging your code
Using the VBE’s built-in debugging tools
Presenting a handy list of bug reduction tips
If the word bugs conjures up an image of a cartoon rabbit, this chapter can set you straight. Simply put, a bug is an error in your programming. Here, you take a look at the topic of programming bugs — how to identify them and how to wipe them off the face of your module.

Welcome to Entomology 101. The term program bug, as you probably know, refers to a problem with software. In other words, if software doesn’t perform as expected, it has a bug.

Fortunately, the vast majority of these bugs are relatively obscure and appear in only very specific circumstances.
