Thank you for confirmation, Sz! Sorry I pestered you on s'thing that was actually work-out-able!No doubt the effect of my favourite red!Just one other query you can answer privately: how come the proper e-mail address you gave me didn't work this time ("please correct the address"!)so I had to use the one you don't often look at? I always thought computers were perfectly REASONABLE, but mine keeps doing things I can't explain!
Anyway now for a conentrated attack on Harpers (after local jumble sale -- the source of many an incredible bargain in the past). I wonder how Aristo is getting on with the puzzle -- that is, when he's eventually free of other burdens...See you for the solution some day in the near future, I hope. So long for now, and thank you again! "Gled" (as he christened me).
