   TO USE THIS FEATURE YOU NEED A PLOTMTV.RC FILE IN THE COURRENT WORK DIRECTORY,
   WHICH ENABLES THE PLOTSETS CALLED:   "direct1" and "direct2"

   in other words: plotmtv.rc should include  at least these lines :
   :direct1 
   %xlabel=""
   %ylabel=""
   %xlog=On
   %ylog=Off  
   %boundary=True
   EOF;
   :direct2 
   %xlabel=""
   %ylabel=""
   %xlog=On
   %ylog=Off
   %boundary=True
   EOF;
   # end of mplot.rc
   
   you can replace the words "True"(or "On")  with "False"(or "Off") and vice versa
