That's a different bug i think, for the same reason, the insert menu
crashed in the waveform sample too.  Bob's workaround was to use #local
and #undef.

Where can I get this file? I could only find the waveform.bmp, but no
.pov for it.

I tried with #local and #undef, but no success so far. Well, I added
the array to still access the calculated function, else there would
be no point for my code..

#local A = array[10]

#local I = 0;
#while(I < 2)       

   #local C = pigment { crackle }                       
   
   #local CF = function { pigment { C } }  
   
   #local A[I] = function { CF }
   
   #undef CF 
    
   #undef C
          
   #local I = I + 1;
#end 

Thanks for this reply and any other suggestions. In case there is
no easy work around, I just wait for the next beta :) (b5 crashes
all the time, and b4 refuses to work.. so not much choice..)
Probably it's not the best idea to develop with a beta anyway, I
still have constants at odd places, because of an earlier bug :)

Maybe you should try beta 6?

It's named 'Attributes.pov' in the Insert Menu directory.

Many thanks. By looking at the code there, I think I found out how to get it
working. In my modified version I was using the wrong syntax for storing the
function in the array..
