The following code was fine in megapov but generates this message in
3.5:
function {( ((y-5.5)+PFWaves(x+10,y,z)* <----ERROR
Parse Error: Expected '.', * found instead
Have I missed something about the way functions work in 3.5?

You should read the documentation more carefully.
Your PFWaves function is a pigment function which returns a color. You
can't use a color in another function which expects a float. If you want
to use the pigment function in another function, you have to specify what
to do with the color returned by it. This is done with the dot operator.
The most common use is .gray (ie. PFWaves(x,y,z).gray) but you can also
use .x, .y, .z and so on.

many thanks, I hadn't realised .gray existed! Found it in the docs now.

They are pretty hidden, that's true. They can be found in section 6.5.4.2.
