I've only rediscovered it to try the baked textures, although I knew it was
being talked about several years ago. Not a lot I can do with it yet, very new
thing to me and I'm not very good with complicated works like it anyhow.

I thought it might be the "dictionary" portion causing this, C. Lipka recently
added, and I keep using the latest alpha version that's available.
That was only around a couple months or so. Found I still have an earlier
version from April this year so checked it and 'prefix' is not a keyword, like
the original 3.7 executable.

So again, I suspect prefix got added and those meshcam files use lower case
identifiers almost exclusively. I haven't looked all through it but I think that
might be the only place prefix is used.

The long concatenate line seems okay, I just didn't post the whole thing before:

  #declare
mesh_file=concat(concat(concat(concat(concat(concat(prefix,str(image_width,0,0)),"x"),str(image_height,0,0)),"-angle_")
,str(c_angle,0,0)),".inc");

Of course, now with current alpha versions of POV-Ray 3.7.1 (Win64 at least) the
word needs a change to Prefix instead of prefix to be able to parse and render.
