System Variables Overview

System variables are built-in variables that Visual FoxPro creates and maintains automatically. They are designated as PUBLIC by default, but you can declare them as PRIVATE.

NoteNote

Recent Visual FoxPro features have replaced the functionality of many system variables. For more information, see the description for each system variable and Backward-Compatible Language Elements.

The following table lists the types of Visual FoxPro system variables and their designation in expressions.
