I think he means that when you set the Subset_End_Frame in the ini file that 
the value you set it to is displayed in the message stream when you use the 
debug command in POV-Ray to display the final_frame preset variable. The 
same happens when you use the command line option +EFn to set the subset end 
frame.

The documentation says that the final_frame variable available at run-time 
in the SDL will contain the value set using Final_Frame, but from my tests 
this doesn't seem to be the case if a subset end frame is defined.

I rendered the following two frames and got the following results from the 
debug commands:

// Command line options  +kfi0 +kff10 +sf5 +ef6

camera { location <0,2,-2> look_at 0 }
light_source { <-5,30,-10> 1 }

#debug concat("Final Frame  : ",str(final_frame,3,3),"\n")
#debug concat("Initial Frame: ",str(initial_frame,3,3),"\n")
#debug concat("Frame Number : ",str(frame_number,3,3),"\n")


// Rendering frame 5 of 6
//
// Final Frame  : 6.000
// Initial Frame: 5.000
// Frame Number : 5.000


// Rendering frame 6 of 6
//
// Final Frame  : 6.000
// Initial Frame: 5.000
// Frame Number : 6.000

Not what I would have expected from the documentation.

Chris B.
