Library /sys$common/syshlp/lse$clihelp.hlb Features, CMS Interface  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  LSE V3.0 provides for invoking DEC/CMS  from  the  LSE  command  line
  using  the  CMS  command.  Also, when LSE must access a file from the
  directory that is the user's CMS library, LSE will automatically  use
  CMS to FETCH the file.  LSE also has a RESERVE command to reserve the
  element in your current CMS library that has the same name  and  type
  as  the  file associated with your current buffer.  The UNRESERVE and
  REPLACE commands also provide the corresonding CMS operation for  the
  file in your current buffer.

  See  the  manual  for  information  "File   Manipulation"   and   for
  descriptions  of  the  following  new or enhanced commands related to
  source code management and DEC/CMS:

        CMS
        GOTO FILE
        GOTO SOURCE
        READ
        REPLACE
        RESERVE
        SET CMS
        UNRESERVE
