Command_Parameters

directory-specification

   Specifies one or more existing CMS libraries in the current
   library search list. The directory specification must conform
   to OpenVMS conventions; it can also be a logical name which translates
   to a search list. If you specify more than one OpenVMS directory, you
   must separate the directory specifications with commas. Wildcards
   are not allowed.  If you do not supply a directory specification,
   CMS removes all libraries from the current library search list.
