Question concerning genprism

Hi all:
I’m learning Radiance and ran into an issue concerning genprism. According
to the book, I typed down the command below. Whenever I tried to oconv the
material1.rad & stool_1.rad, it gives me errors below. Someone using Linux
system can fix the issue by setting the PATH environment. I already set the
PATH, RAYPATH, and MANPATH in both .profile and .bashrc. I’m wondering if
there’s any other way of solving the problem.
Thank you in advance.

Try removing the "\" and just joining the lines in your file, like so:

# using the modifier brown_satin_paint. create a polygon. named stool_top
!genprism brown_satin_paint stool_leg_se 4 0.7 -0.7 0.7 -0.6 0.6 -0.6 0.6 -0.7 -l 0 0 2.5

I'm guessing that the Windows command line doesn't like the escaped newlines.
