Qualifiers

/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. If this
   qualifier is not specified the status of this attribute remains
   unchanged.

/EXTENDED_FILENAMES
   Change the attribute of a CMS library to allow the use of extended
   file names. This qualifier is only available on OpenVMS V7.2 and
   later. Use /NOEXTENDED_FILENAMES to change the attribute to disallow
   the use of extended file names. If this qualifier is not specified
   the status of this attribute remains unchanged.

/KEEP
   Instructs CMS to not delete all versions of a file used to create
   a new element or generation. If this qualifier is not specified
   the status of this attribute remains unchanged.

/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.

/LONG_VARIANT_NAMES
   Change the attribute of a CMS library to allow the use of long
   variant names. Use /NOLONG_VARIANT_NAMES to change the attribute
   to disallow the use of long variant names. If this qualifier is
   not specified the status of this attribute remains unchanged.

/OCCLUDE[=option,...]
   Controls whether CMS selects the first instance of the specified
   object, or all instances of the specified object in the library
   search list. The options field contains one or more keywords
   associated with the name of the object. The options field can
   contain the following keywords:

      ALL--equivalent to OTHER
      OTHER (D)
      NOOTHER
      NONE--equivalent to NOOTHER

   You can specify either ALL, NONE, or the [NO]OTHER keyword.

   By default, CMS performs occlusion for all objects; that is, CMS
   selects only the first occurrence of a specified object.

/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
   can it be a subdirectory of a CMS library directory. If you use
   the MODIFY LIBRARY command on a search list consisting 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 uses one 
   reference copy directory for the entire search list, not one 
   reference copy directory for each library in the search list. 

   Use the /NOREFERENCE_COPY qualifier to remove the connection 
   between the current CMS library and the current reference copy 
   directory. Wildcards are not allowed.

/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 keyword ORIGINAL 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 keyword STORAGE_TIME 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.
