OCT-2002  Recompiled for MS Windows by Urs Rohrer (PSI).


Used compiler is Digital Visual Fortran Version 6.

fl32 -c  -Ox ray1.for
fl32 -c  -Ox ray2.for
fl32 -c  -Ox ray3.for
fl32 -c  -Ox ray4.for
link ray1.obj ray2.obj ray3.obj ray4.obj @listopt

listopt:
-out:raytrace.exe
-machine:i386
-subsystem:console
-entry:mainCRTStartup
-stack:32760,4096
-defaultlib:dfor.lib

How to run RAYTRACE best under Windows:
=======================================
It is actually a 32-bit DOS program. So you may open the command prompt box
(icon with C:\ on black background, you find it under Programs -> Accessories)
and switch with e.g. C: and cd \RAYTRACE to the directory e.g. C:\RAYTREACE where
you have e.g. stored the raytrace stuff. Then you just type raytrace and in case
it finds raytrace.exe and RAYTR.MAG in this directory, it will execute the job
and produce the desired ASCII output files.
