Hi,
I've got a little problem with recursion and include-files.

I write a macro with recursion which works well. Now I want to write some of
the object defining (I'm not sure, about that word) in another Include(or
Pov)-file. In that file are also some if-commands with variables, which I
defined in the actual file. Than of course the massage came "too many
nested include files". I think that came because of the recursion, but I'm
not sure.

Is there any other possibility, or must I leave the object defining the
actual file?

Please help, and sorry for my bad English.

A short scene demonstrating the problem would be of great help
answering your question.

A solution would be to include your file(s) before the recursive part. If the included
file is an 
object deffinition, you can make it a free standing object.
#declare MyObject = object{#include<your include>}

Then, you use MyObject in your recursive macro/function.

Here's a simple scene, to see, where my problem is (my actual file is much
more complexer)
The main-file:

#macro Test (Art,P1,P2,n)

#local P3 = P1+ (P2-P1)/2 ;

#include "Obj_def.pov"
#include "Typ_def.pov"

union{

#if (n=0)

cylinder{P1,P2,0.5}
object{Ba}

#else

cylinder{P1,P2,0.5}
object{R}

#end
}
#end

Now, the Include-file "Obj_def.pov":

#if (Art = 1)
#declare B = box{1,1}
#end

#if (Art = 2)
#declare B = box{1.1,1.1}
#end

And this is the file "Typ_def.pov". I think there's the problem:

#if (Art = 1)

#declare Ba = union{
object{B translate P1}
object{B translate P2}
object{B translate P3}
}
#declare R = union{
object{Test (Art,P3,P3+vrotate(P2,<0,0, 45>),n-1)}
object{Test (Art,P2,P2+vrotate(P2,<0,0,-45>),n-1)}
}

#end

#if (Art = 2)

#declare Ba = union{
object{B translate P2}
object{B translate P3}
}
#declare R = union{
object{Test (Art,P1,P1+vrotate(P2,<0,0, 45>),n-1)}
object{Test (Art,P2,P2+vrotate(P2,<0,0,-45>),n-1)}
}

#end

Thanks for your answers.

Now, include those before your recursive macro.
In the macro, just call the 2 macro instead of including the files.

Thanks, it works great.
I changed yours a little bit (e.x.:
object{ObjMac (Art)
object{TypMacB (Art,Blatt)
object{Ba}}}
), but the idea is yours.

Thanks
