In POV 3.6, you can achieve this using:

  #if (strcmp(DoorModel,model_101)) ...

In POV 3.7, POV-Ray's comparison operator works for strings, too, so you can
also use:

  #if (DoorModel = model_101) ...

(Note the single equals sign; POV-Ray does *not* use C/C++ style operators.)

No, that's only possible with float values, even in 3.7.

Out of curiosity: Are you sure you want to use strings for the model
identifiers? A numeric id would do, I guess. After all, you can always use
those identifiers you have, like model_101, so you don't have to memorize all
the - possibly cryptic - ids.

If you absolutely need to work with strings for model identifiers, I suggest
translating them to numerical ids first, by looking them up in an array.
