Qualifiers

/AFTER[=directory-specification]
   Instructs CMS to insert new libraries into the existing library
   search list immediately following the existing specified
   directory. The specified directory must be in the existing
   library search list. If you omit the directory specification,
   CMS automatically adds the libraries (in the order you specify) to
   the end of the list. You cannot specify both /AFTER and /BEFORE on
   the same command line. If neither /AFTER or /BEFORE is specified,
   the CREATE LIBRARY command's library list supersedes any existing
   search list.

/BEFORE[=directory-specification]
   Instructs CMS to insert new libraries into the existing library
   search list immediately in front of the existing specified
   directory. The specified directory must be in the existing
   library search list. If you omit the directory specification, CMS
   automatically adds the libraries (in the order you specify) to the
   front of the list. You cannot specify both /AFTER and /BEFORE on
   the same command line. If neither /AFTER nor /BEFORE is specified,
   the CREATE LIBRARY command's library list supersedes any existing
   search list.

/CONCURRENT (D)
   Specifies whether elements in a library can have multiple 
   reservations by setting the concurrent attribute on the library.
   Use /NOCONCURRENT to disallow multiple reservations.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/CREATE_DIRECTORY
   Instructs CMS to create a directory to contain the library if the
   directory does not already exist. /NOCREATE_DIRECTORY is the default.

/EXTENDED_FILENAMES
   Used to create a CMS library that allows the use of extended file
   names. This qualifier is only available on OpenVMS V7.2 and later.
   Use /NOEXTENDED_FILENAMES to create a CMS library that does not allow
   the use of extended file names. /NOEXTENDED_FILENAMES is the default.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/KEEP
   Instructs CMS to not delete all versions of a file used to create
   a new element or generation.  /NOKEEP is the default.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/LOG (D)
   Controls whether CMS displays success and informational messages
   on the default output device. By default, if the command executes
   successfully, CMS displays a success message. If you specify
   /NOLOG, success and informational messages are suppressed. Any
   warning, error, or fatal error messages are displayed regardless
   of whether /LOG or /NOLOG is specified.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/LONG_VARIANT_NAMES
   Used to create a CMS library that allows the use of long variant names.
   Use /NOLONG_VARIANT_NAMES to create a CMS library that does not allow
   the use of long variant names. /NOLONG_VARIANT_NAMES is the default.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/REFERENCE_COPY=directory-specification
   Specifies a valid OpenVMS directory to be used for reference copies
   of library elements. The directory cannot be a CMS library, nor
   should it be a subdirectory of a CMS library directory. If you use
   the CREATE LIBRARY command to create a search list of more than
   one library, you should specify a reference copy directory for
   each library in the search list. If you specify only one reference
   copy directory for more than one library, CMS creates one library
   for the entire search list, not one library for each library in
   the search list. Wildcards are not allowed.
   /NOREFERENCE_COPY is the default.
   Use MODIFY LIBRARY to change this attribute on an existing library.

/REVISION_TIME[=option]   Controls whether CMS uses the original file revision time or the
   file storage time when a file is retrieved from the CMS library.
   The options field can contain of the following keywords:

      ORIGINAL (D)
      STORAGE_TIME

   Use the ORIGINAL keyword to indicate that the original revision
   time of files placed in a CMS library should be restored unchanged 
   upon their retrieval.  This is the default behavior.  

   Use the STORAGE-TIME keyword to indicate that the time when a file
   was stored in a CMS library (through a CREATE ELEMENT or REPLACE 
   transaction) should be substituted for its original revision time 
   upon retrieval.
   Use MODIFY LIBRARY to change this attribute on an existing library.
