The syntax you've shown is that which I created for my Automatic Clock
Modifier macro file.  This means the From (), To (), and Using () statements
are not internal to POV-Ray, but functions added by including my macro file.
Therefore, to use this syntax you must first include the macro file
(presuming you have downloaded it from http://www.geocities.com/ccolefax and
installed it properly):

   #include "autoclck.mcr" // Before any animation statements!

Having done that you can animate the scene using INI file or command line
settings, and your camera should indeed look at <-56, -34, 1> for the first
half of the animation before accelerating to <-1068, -34, 1>.
