successful tparse transition
    Facility: EFI$CP, The OpenVMS EFI Partition Control Program
    Explanation: an internal state transition match has succeeded
    within the parsing logic; the attempted transition matches the
    input data.
    User Action: this status is internal to the FAT filename parsing,
    and should not be generally visible outside the application. This
    message indicates a state transition match, and this status has
    little direct meaning outside of its use within the lib$table_
    parse processing.
