Remarks

Prefixes aren't required, but are recommended as good programming practice. Using a prefix does not dictate the contents of a field — in Visual FoxPro, prefixes are used only as a naming convention. For example, adding the prefix "d" does not check that the contents of a field is a date, but it does help you remember the data type contained in the field.

For more information, see Visual FoxPro Naming Rules.
