Re: plotting data in a separate directory

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Helge,
           While specifiying path to a file, you must use quotes
like;

	yes? use "/home/DATA/mydata.dat"    ! full path
                                            !   or
        yes? use "./DATA/mydata.dat"        ! relative to current dir.


  To use your present sript, define a new variable like;

        yes? define symbol qts = \"
  
   while setting the path to the symbol  put ' " '  & ' . ' in case 
   of relative path 

      yes? define symbol RESULTS=($qts).($DIR)\/($LABEL).data($qts)

      yes? define symbol VGRID=($qts).($DIR)\/($LABEL)-grid.data($qts)


Hope this helps

With Regards
