UPDATED()

    UPDATED() returns a logical true (.T.) if the last READ changed any of
    the data in the associated GETs.

Syntax

    UPDATED()

Usage

    Each time READ executes, it resets UPDATED() to false (.F.).  Note that
    within a READ, a change to any GET sets UPDATED() to true (.T.).
    Subsequent testing of UPDATED() within a SET KEY procedure or VALID
    reflects this status.
