0, Chapter 4 is the first of three chapters
2, devoted exclusively to using program
5, code--the statements, keywords, and
8, programming structures that form the core of
10, a Visual Basic application. First, you'll
13, learn how to use variables to store
15, important information in your program.
18, Variables help you manage data in event
20, procedures and are especially useful with
22, two dialog box functions named InputBox
26, and MsgBox. Next, you will learn how to
29, use specific data types to fine-tune the
32, size and content of your variables and
35, streamline your calculations. The data
37, types you'll learn about include Integer,
40, single precision floating point, string,
43, and variant. Finally, you'll learn how
47, to use mathematical operators such as
49, addition and multiplication to create
51, formulas in your programs. With formulas, you
55, can perform a number of useful tasks,
57, including totaling a column of numbers or
60, computing the sales tax for an item.
