HELPLIB.HLB  —  INITIALIZE  Qualifiers  /LABEL
       /LABEL=option

    Defines characteristics for the magnetic tape volume label, as
    directed by the included option. The available options are as
    follows:

    o  OWNER_IDENTIFIER:"(14 ANSI characters)"

       Allows you to specify the Owner Identifier field in the
       volume label. The field specified can accept up to 14 ANSI
       characters.

    o  VOLUME_ACCESSIBILITY:"character"

       Specifies the character to be written in the volume
       accessibility field of the OpenVMS ANSI volume label VOL1
       on an ANSI magnetic tape. The character may be any valid
       ANSI "a" character. This set of characters includes numeric
       characters, uppercase letters, and any one of the following
       nonalphanumeric characters:

       ! " % ' ( ) * + , - . / : ; < = > ?

       By default, the OpenVMS operating system provides a routine
       that checks this field in the following manner:

       o  If the magnetic tape was created on a version of the
          OpenVMS operating system that conforms to Version 3
          of ANSI, then this option must be used to override any
          character other than an ASCII space.

       o  If a protection is specified and the magnetic tape conforms
          to an ANSI standard that is later than Version 3, then this
          option must be used to override any character other than an
          ASCII 1.

       If you specify any character other than the default, you
       must specify the /OVERRIDE=ACCESSIBILITY qualifier on the
       INITIALIZE and MOUNT commands in order to access the magnetic
       tape.
