is it possible to change values that have already been declared? like,
#declare a = 2
#declare a = a*a
#declare a = a*a

and so on...?

  Why don't you try?

-- 
main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Certainly. In fact, #while loops are generally done using this.
Example:

#declare C=0;

#while (C<10)
#declare C=C+1;
#end

Tell me more about Pov-Ray functions please

Post a reply to this message

There is a great source of information about the POV-Ray functions,
keywords, objects, etc. It covers everything, and is well written and
easy to understand. It includes a tutorial section, and a reference
section.
It is the manual. pov.doc. It comes with POV-Ray, in the same archive as
the rest of the download. Please at least try to find the answers to
your questions in it, it is faster than the newsgroups anyway.
In addition, depending on what platform you are on, there may be help
accessible directly from the POV-Ray application program.
