VMS Help MMS, CMS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    If CMS is installed on your system and your source files  are in  the
    current default  CMS library,  MYPROG.EXE may be built  from the  CMS
    library when you issue the following command:

         $ MMS/CMS

    This command causes MMS to fetch the description file, if  necessary,
    and source files from the CMS library, and perform the actions needed
    to create an up-to-date MYPROG.EXE.

    If a module, for example A.BLI, is replaced in the  CMS  library  (by
    you  or  anyone else), thus causing a later version of A.BLI to exist
    in the library, the command

         $ MMS/CMS

    causes MMS to fetch the new CMS element A.BLI, compile it, add it  to
    the MYPROG.OLB library, and produce a new MYPROG.EXE by executing the
    LINK command.
