You  can  use the Tape InQuiry program on the ISPF
            LOCAL panel to display and update the  information
            stored  in  the tape management catalog about your
            tapes.  The information in the catalog is automat-
            ically updated by the operating system when a tape
            is read or written and is used  by  the  operating
            system  to  manage  the  tapes in the SMC tape li-
            brary.  The stored information includes expiration
            date, DCB information, creating jobname  date  and
            time,  files  on  the  tape, tape location, a user
            'comment' field, and the owning account (TACCT) of
            the tape.
 
            You can specify the tape record you work  with  by
            providing  either  the volume serial number of the
            tape, a fully qualified data set name or the rela-
            tive generation of a GDG which is cataloged in the
            MVS system catalog such as J1234.P88888.DUMP(-1).
 
            When you start TIQ you will be asked to provide  a
            password.  The  default password is INQ, which al-
            lows you to display all the information kept about
            a tape.
 
            The password UPD allows you  to  display  informa-
            tion,  update  the  expiration  date  and  comment
            fields,  and also use the utilities EXPIRE, EXTEND
            and  RETAIN,  which  modify  the  expiration  date
            field.    You may modify only the records of tapes
            whose data set names you have RACF UPDATE  author-
            ity for. (See the note below for information about
            update  authority  when  there is no RACF data set
            profile covering the data set name.)
 
            -The EXPIRE utility sets the expiration date to
             today.
 
            -The RETAIN utility resets the expiration date
             in days from creation date (CDATE).
 
            -The EXTEND utility adds days to the expiration
             date if the existing expiration date is a real
             date, i.e. you could EXTEND an expiration date
             of 1999/030 by 60 days, but could not EXTEND
             an expiration date of CATALOG or PERMANENT.
 
            Note:    RACF data set profiles generally  have  a
            high-level qualifier of Jnnnnnn, where nnnnnn is a
            legitimate  RACF  group.  If a tape has a data set
            name for which there is no RACF profile, for exam-
            ple DSN=MY.FILE1, then permission  to  update  the
            tape  record  is  based on connection to the group
            which owns the tape. The group which owns the tape
            is in the field TACCT.
