Hello mr. art

Thanks for replying.

Right now I did try to replace the s with other
variable names, but it didn't stop those ever-
changing error messages.

I'm just using plain POV-Ray (v3.1g) for Windows 
(Not MegaPOV).

I looked up reserved identifiers and keywords in
the help file, but I could not find 's' listed 
for this plain version of POV-Ray.

Regards

Tor Olav
