It ought to be.

Write a tiny .pov file that outputs the value of input_file_name to the debug
stream.   Rename the file.  Render it again.

Since you're opening the file as the main .pov file, that's what input_file_name
gets defined as.

If you write another .pov file that INCLUDES the first .pov file, then it's the
main file that gets its filename assigned to input_file_name.

That's why this ought to be a good solution for you.

Just try it - you'll see.
