Language Reference

You can use the Visual FoxPro interface to perform many database tasks and develop applications for cataloging, tracking, and processing information. Knowing more about the Visual FoxPro programming language enhances your ability to access the power of Visual FoxPro.

Like other programming languages, the Visual FoxPro programming language makes it possible for you to work with various types of data, such as numbers and character strings. You can store data of these various types in tables, arrays, variables, and other data containers. To manipulate data, you can perform operations, such as addition and concatenation. In addition to operators, Visual FoxPro provides a rich set of commands and functions, so you can protect, display, and manage your data.
