Control Flow

Left unregulated, a program proceeds through its statements from beginning to end. Some very simple programs can be written with only this unidirectional flow. However, most of the power and utility of any programming language comes from the ability to change execution order with control statements and loops.

Control-flow statements allow you to regulate the flow of your program's execution. Using control statements, you can write Visual Basic code that makes decisions and repeats actions. Another useful statement, With...End With, lets you execute a series of statements without having to requalify an object.
