VMS Help ANALYZE, /AUDIT, /SELECT, FIELD_NAME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    FIELD_NAME=(field-name,...)

    Specifies the name of the field that was modified. ANALYZE
    /AUDIT uses the FIELD_NAME criterion with packets containing
    the original data and the new data (specified by the NEW_DATA
    criterion).
