In [[Visual Basic Comparison and Logic]] we looked at how to use Visual Basic logical expressions to decide is something is ''True'' or ''False''. Much of the art of programming involves writing code that makes decisions based on one or more criteria. Such decisions define which code gets executed and which code gets by-passed when the application is running. This is often referred to as ''flow control'' since it controls the flow of execution.
