If you want to output PN, then why do you output B ?! ;-)

By defining it /before/ you include the file??

But from the code I guess you'll also want more than one "U-bar" in the 
long run anyway, with different lengths - your current code cannot 
accomplish that anyway. You should have a look at POV-Ray's macro 
mechanism for that. Essentially, macros are the only way in POV-Ray to 
"pre-define" anything without specifying all the parameters beforehand.
