	Thanks !
	Ok, it works fine if I do something like:

#if(clock=0)
  box{ ...  label thebox }
#else
  modify{ thebox  ... }
#end

   ... but NOT if doing the following:

#ifndef(persist)
  box{ ...  label thebox }
#else
  modify{ thebox  ... }
#end

#declare persist = 1;

	Here the box is never modified (my ini file still contains
Persistent_Animation = yes). Same result if I put the #declare
within the #ifndef condition. Again I may do something wrong...
[I already noticed a strange behaviour of #ifdef/#ifndef tests
in official POV-Ray also]. Any clue ?
