Function LUpdate() Foundation
Returns the date of the last change to a database file.
LUpdate() --> dDateThe return value of LUpdate() is a date value indicating the date of the last change to the database file in a work area. If no file is open in the work area, an empty date is returned (DtoC("")).
The database function LUpdate() returns the date of the last change to a database file in a work area. If the function is used without the alias operator, the date of the last change to the file in the current work area is returned. During write access to a database file, the date last modified is updated only when the file is closed.
// The example shows the return value of LUpdate() and
// demonstrates how the date last modified is updated only
// when the database file is closed.
