Can You help me ?

Here is my example file :


camera{   location z*50    look_at  <0,0,0>  }

light_source{ <20,20,50> rgb <1,1,1> }

  #declare Name = concat("\"FR",str(11,0,0),".tga\"")   // this should
be  "FR11.tga"

   sphere {0, 10
    pigment {image_map {tga "FR11.tga" map_type 1 interpolate 2 transmit
255, 1.0}}
 // pigment {image_map {tga Name map_type 1 interpolate 2 transmit 255,
1.0}}       //That's what I wanna write!

      finish {ambient 0.3 diffuse .8}    }



   /*   Hello,
      please have a look at this very short pov.file

      I'm working with Megapov and I'm wondering about strings:

      Why can't I write Name instead of "FR11.tga"  inside the image
map.
      I like to change the number of the picture (11 to 12 to 13 etc.)
      for loading different pics during an animation !!
      How can I do this ?
      Can I do something similar ?
      Thank You for thinking it over.

      Best wishes
      Luck and Blessing

Try :

#declare Name = concat("FR",str(11,0,0))

or even

pigment{image_map{tga concat("FR",str(11,0,0))}}

Note that to debug this kind of problem you can always write
#debug concat(Name,"\n")
to see what's going on.

You are putting quote characters inside the string, so POV-Ray looks for 
a file titled '"FR11.tga"'. You need to remove the \" sequences.

Also, this question doesn't have anything to do with patches, it would 
have fit better in povray.newusers, povray.advanced-users, or 
povray.general. Please read the message "Welcome To the POV-Ray News 
Groups" in povray.announce.frequently-asked-questions.
