As a way to aim at two birds with one stone, please see:

http://wiki.povray.org/content/User:Wfpokorny/DensityFile/arraycoupleddf3s

then cut and paste that link as an address into your browser. It should 
be you open that file in my branch on github. At the very bottom of that 
include there is an example use of a bitwise_and.

That wiki page opens for me and - I hope - for you?

On your page creating that wiki error you can still view the source and 
it includes an index pointer function at the top. I think this is the 
issue. Jim is the editor of those pages so perhaps he can sort it.

I see now too my main way into the documentation at:

http://wiki.povray.org/content/Reference:Keywords

no longer works. Hopefully this can be fixed relatively soon.

Aside: If you are working with a git clone (or github download) you can 
locally open up a reasonably current version of the documentation in a 
browser by opening the index file at:

    <local povray directory>/doc/html/index.html.

The wiki though holds the most up to date docs. Other forms are created 
by Jim less often.

Aside 2: I've for a while not been able to create links out of the wiki 
as another issue which has crept in over time as has been reported 
elsewhere too.
