This is a bit similar to SharkD's question above, but I wonder if it is
possible.
What I want to do is the following:
#local PoserName = "Beggar_";
#include concat(PoserName, "POV_geom.inc")
#local ObjName = object {PoserName}
The first two line of code work correctly, but the third one generates a
parse error of course, as a string identifier instead of an object is found.
How can I make this work?

All the best,

similar problem with wanting to include a frame number in the name of
the object (in PovRay) until I saw that you can define in PoseRay what
you want to name the object.

I assume that an object called 'Beggar_' is declared within the include
file?
If so you could use the Parse_String(String) macro. This macro takes a
string, writes it to a file, and then includes that file, effectively
evaluating the string, so:
#include "strings.inc"
Parse_String(concat("object {",PoserName,"}"))
should do it. Warning. I didn't test this for syntax errors.

Chris B.

Yes, I know this posibility, but that is not my problem. I try to simplify a
POV-Ray test scene for Poser figures that I use regularly, where I simply
have to give the generic name of the figure only once.

Yes indeed.

Perfect Chris! It works. I just changed my code line to:
#local ObjName = Parse_String(concat("object {",PoserName,"}"))
and used that for further work in the scene.

PS I shall have to look into strings.inc to discover what more is hidden
there :-) Fact is that I do not know *everything* that POV-Ray offers....

Fun facts to know:
The Parse_String macro actually "inlines" the string by writing it to a
temporary file, which it then includes.

Nor do I. :o)
That's one great thing about using such a mature application. It's got
depth. Lots of handy tricks and features just waiting to be explored.

Which makes one marvel (and slaver) at all those hidden goodies :-)
