  In this case the #if statement doesn't stand for conditional code
execution (like 'if' in C) but for conditional parsing instead (like '#if'
in C) (it's often a bad thing that povray doesn't distinguish between these
two things).
  Conditional parsing (or compiling) is always a tricky thing. It makes
the code hard to understand almost always. It's also very hard to indent.
  In this case I usually do something like this:

#if(A>0)
  union {
#end

    sphere { ... }

#if(A>0)
    sphere { ... }
  }
#end
