   The folks who designed VMS can speak for themselves, but what I've
   heard is that they were well aware of UNIX, it's featurs, and it's
   limitations.

   A lot of past work at also DEC influenced VMS, but some of that work was
   also influenced by earlier work outside DEC such as UNIX.

   The only thing I've heard substantially influenced by UNIX, and also
   attempted various ways in earlier DEC operating systems, was the
   now ubiquitous nesting of directories inside directories in a file
   hierarchy.  Even then, there were influences that lead VMS to a
   per-disk hierarchy, rather than UNIX style mount points.

   So VMS users can be glad that user names and directory names are
   strings, that subdirectories are part of the file system, but were not 
   done in the TOPS-10 nor TOPS-20 style.
