    FUNCTION = A record containing Dump Domain Global Statistics
           This DSECT describes the global system dump statistics
           Produced by the Dump Domain. A single instance of the data
           is produced by the Dump Domain. Additional copies may be
           created by the statistics domain, statistics utility
           programs or user programs.
           The data consists of a header plus a block of statistics
           for the Dump domain.
    LIFETIME = Created when the Dump Domain is initialised and
               exists for the lifetime of the domain manager.
    STORAGE CLASS = varies
