If you are really trying to use a " - " as a part of your declared
object name then you will get and error. Perhaps you should be
recieveing a different warning but I think what is happening is that
Pov goes through the loop until it processes all of the interations
and then starts looking for directions on how to proceed. At this
point it has been parsing for quite a while and then it hits a
directive from you to subtract Tit from Hull and starts looking for
the definition of the terms. Using Tit-Hull is an illegal operation
because the minus sign is a reserved symbol. You should instead use
an underscore like this #declare Tit_Hull = whatever .
