I am having trouble converting some of my #while loops into recursive macros
(where you call the macro from inside the macro). I seem to remember reading
something about it in the docs, but can't find it now. I can post some
specific problems if needed, but the recurring problem is "too many nested
macros", and if I don't get that, I get unexpected results that seem to
stem from lost values in variables.
Is there a tutorial around? Or does someone remember where it is in the
docs?

In general, try to avoid recursion in POV. its far slower and more
memory consuming than a #while loop. (or a set of them).
i don't remember the limit, but it's easy to test it...
#version 3.1;
#macro test(N)
#debug concat(str(N,0,0),"\n")
test(N+1)
#end
test(0)
camera{ <0,0,0>,<1,1,1> }
sphere { <1,1,1>,0.02 pigment{colour rgb 1}}
That should suffice to count them ..

Considering the trouble I am having, I will find it easy to avoid
recursion. I thought it would be an easy way to change parameters while
zooming into a fractal, but I begin to doubt if it is worth it.

Blows up at 97, I was thinking about a million or so.

Hmm, mandelbrot ???
Well, warp made a fractal in pov... Don't know where it is though..
