*P*      NAME:         FIXHGP
*P*
*P*      PURPOSE:      PROVIDE SOME SYSTEM INITIALIZATION FUNCTIONS,
*P*                    PUBLIC FILE HGP RECONSTRUCTION, AND PRIVATE
*P*                    PACK HGP RECONSTRUCTION.
*P*
*P*      DESCRIPTION:  AT INITIAL TAPE BOOT, BUILD COPY OF HGPS AND
*P*                    WRITE TO ALLOCAT DATA.  ALLOCATE GRANULES FOR
*P*                    ACCOUNT DIRECTORY FDA AND DUAL, INITIALIZE AND
*P*                    WRITE THEM.
*P*
*P*                    AT SYSTEM BOOT (WHETHER CRASH RECOVERY, COLD
*P*                    BOOT OR BOOT AFTER ZAP) FIX IS ENTERED BEFORE
*P*                    GHOST1.  IF A RECOVERY BUFFER EXISTS, SOME
*P*                    ITEMS ARE PROCESSED (THE OTHERS WILL BE DONE
*P*                    IN RECOVER2 IN GHOST1).  IF CRASH WAS X'89'
*P*                    (ALLOCAT) OR OPERATOR REQUESTS IT, AN HGP
*P*                    RECONSTRUCTION OF THE PUBLIC FILE SYSTEM IS
*P*                    PERFORMED.
*P*                    IF A RBBAT RECOVERY FILE EXISTS, NO RBBAT RECOVERY
*P*                    IS DONE.  OTHERWISE, IF RBBAT WAS ACTIVE AT
*P*                    THE TIME OF THE CRASH, HIS DATA IS WRITTEN TO
*P*                    THE RBBAT RECOVERY FILE (:RBBRVR).
*P*
*P*                    FIX EXITS TO GHOST1 BY SETTING GHOST1'S USER
*P*                    NUMBER INTO FIX'S UB:ACP (COMMAND PROCESSOR)
*P*                    AND ISSUES AN M:EXIT CAL.
