Hi,

   I have often had the problem that POV-Ray for Windows does not succeed in
parsing what seems to be correct code. For example, with the latest Windows
version, if I copy verbatim (cut-and-paste) the sky sphere example from the
docs (section 2.3.2.4),

  sky_sphere {
    pigment {
      gradient y
      color_map {
        [ 0.5  color CornflowerBlue ]
        [ 1.0  color MidnightBlue ]
      }
      scale 2
      translate -1
    }
  }

with nothing else in the file, I get the messages below.

Appreciate any help. Thanks.

There's your problem. CornflowerBlue is not declared. Did you put

#include "colors.inc"

at the beginning (assuming CornflowerBlue is declared in colors.inc)?

Assuming you included colors.inc, I can only suggest reinstalling POV-Ray 
(maybe your colors.inc is corrupted in some weird way)

(I guess you mean section 3.3.2.4.)

The docs sometimes don't mention the use of standard include files, such as
"colors.inc" in this case.

This typically leads to "Parse Error: Expected <WhatEver>, undeclared identifier
'<WhatElse>' found instead" messages.

The numbering in the online documentation and the Windows documentation 
differs by one at the top level, so it's 2.3.2.4 in the online version and 
3.3.2.4 in Windows.

So you're both right :-)
