Yes that'w what I mean. It seems that at least in some repects variable
substitution works like I expect it to :-)

The manual is certainly not enough when I walk in and want to do some work
with it. It would be slightly better if I had time to work throug a tutorial
perhaps. But I generally find I don't learn it until I try to use it anyway,
so I still need better documentation.
Perhaps it will come one day!
Thanks Christoph.
