     1.  NTRACE

              NTRACE uses the VAX/VMS LXY11 plot routine package  purchased
         from  Digital  Equipment  Corporation  to  plot lines on the LXY11
         printer/plotter  which  is  the  same  as   the   Centronics   300
         printer/plotter.   If  this library package has not been installed
         on your system , NTRACE will not function.
