Thanks for ALL of that, Jazz Girl !!
You seem to be working harder at it than the compiler... or is that just me saying "sour grapes" because I couldn't do it?
Don't worry about senior moments - I seem to be having a senior LIFE at the moment, with fewer incidents of lucidity (judging by my difficulties in solving these 'ere crosswords!)
Thanks yet again, and sorry for late reply.
Best regards, Chris.
