OK got the variable business and, yes, by "procedures" I had meant macros.

I didn't mean to be totally snarky in my reply message but the write-up
under #debug is by no means clear (in fact #debug is not even listed as a
help topic in my version of POVRay 3.1g) and it ticked me a little to have
the instant (and erroneous) assumption made that I had not read the
documentation..

I also had failed to note the povray.newusers group which, I guess, is where
one should ask for help.

It might help if some people understood that there are a few of us (well me
anyway) who are not IT experts and consequently have to go running off to
look up even simple little things like "IDE".

Having said all that, I also need to add that POVRay has provided me with
hours of amusement.  I do appreciate the incredible amount of very high
quality work done by the POVRay team and, the fact that such a program is
free! is incredible.  I certainly do not wish to denigrate their work in any
way.

Thanks,
