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.
