Hey Torsten!

What is the problem with using File-Output-Macros only?

<code>
#include "colors.inc"

camera {
    location 5
    look_at 0
}

light_source { 100 White }

#macro Thingy(X1,X2,Filename,AutoInclude)
    #fopen MyFile Filename write
    #write(MyFile, "sphere { 0,1 scale ",X1," translate ",X2," }")
    #fclose MyFile
    #if (AutoInclude) #include Filename #end
#end

object {
    Thingy(<1,0.2,3>,2,"thingy.inc",on)
    pigment { Green }
}
</code>

The only problem is that you'll have the overhead of writing to disk /
parsing include-files every render, but that should not be the problem.

HTH,
Florian
