Working with Sub Procedures
The key idea behind working with any type of procedure is to break down your program into a series of smaller tasks. Each of these tasks can then be encapsulated in a procedure, function, or possibly a class. (Classes are discussed in Chapter 9, “Creating Code Components.”) Programming in this manner presents several advantages:
