I was avoiding one line of code for every parameter. And i'm going to
need lots of parameters, as there doesn't seem to be a
'record/struct/class' construction in POV :)

Instead of using the code below:

// pseudo code
#macro example(pos)
   #while
      example(pos)
      #local pos = pos + y
   #end
#end

I'm using now, as you suggested:

#macro example(pos)
   #local var_pos = pos // this is what i have to do additionally
   #while
      example(var_pos)
      #local var_pos = var_pos + y // because this should change the
                                   // local value only
   #end
#end

And it works exactly as I want it to :)

Thanks again for your reply,
