Remarks

Prefixes aren't required, but are recommended as good programming practice. Using a prefix does not dictate the contents of an object variable — in Visual FoxPro, prefixes are used only as a naming convention. For example, adding the prefix "cbo" does not check that the object referenced by the variable is a combo box, but it does help you remember the object referenced by the variable.

For more information, see Visual FoxPro Naming Rules.
