Having selected a suitable encapsulated PostScript graphics device, each KAPPA application will produce an output file in your current directory containing PostScript commands. These files can be examined without needing to be printed by using the ghostview program. By default, the output file will be called pgplot.ps.
Note, subsequent graphics commands will overwrite any file created by earlier graphics commands. For this reason you should rename the output file after running each graphics command. An alternative approach is to assign a unique value to the DEVICE parameter for each graphics command (rather than just allowing it to default to the value of the global parameter set using GDSET). For instance, DEVICE="epsf_l;contour.ps" would cause the command to write its output to file contour.ps.
