VMS Help LIBRARY, /SQUEEZE, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  $ LIBRARY/MACRO/NOSQUEEZE/INSERT MYMACS MYMACS

      This LIBRARY command inserts the macros in MYMACS.MAR into
      the library MYMACS.MLB. Trailing blanks, trailing tabs, and
      comments are not deleted from each macro before its insertion
      into the library.
