I'm making a scene just to learn macros and I've already run into some
trouble. Here is my code:

  object {Cheerio
  translate VRand_In_Object(area, RdmA);
  }

I get an undeclared identifier at VRand_In_Object. Why? I have rand.inc
included. How come VRand_In_Object doesn't work?

The macro is named VRand_In_Obj in the .INC file.

You also don't need the semicolon where you have it.

Thanks! In 7.12.1 it is listed as VRand_In_Object! Where should I report
this?

I posted my fool code in p.t.s-f  I'm making this scene just so I can learn
about macros. I have a few questions. How come the cheerios are alwawys
contained within what looks like a square even though I'm useing a disc in
VRand_In_Obj? Also how can I
get the look to make sure the ceerios don't overlap?

Thanks,
Corey

It's because you are using a disc. VRand_In_Obj() returns points 
*inside* the object, discs don't have an inside (they are infinitely 
thin) so it makes several attempts (specifically, 1000 attempts) before 
eventually giving up and generating a point inside the bounding box of 
the disc. The documentation specifically mentions that this macro only 
works on solid objects. If you use a short cylinder, it will work.
