@Koldo thanks for your endless patience and for all your help.
Yes I've been fumbling for IsValid or IsNull in the autocompletion suggestions and in the built-in help, as a member method - but it never occured to me to look for it as a stand-alone function (I really wouldn't know how, it doesn't jump at me via autocompletion). Trawl the examples, that was the one thing I gave up, in favour of asking yet another silly question.
I don't mean to complain, there are always sweet secrets when learning a new environment, and I sure do recall the old days when we were not spoilt by omnipresent hints and instant help And it's a modern marvel of the world to have a place to ask, and get a friendly answer overnight.
Once again you have patiently answered several facettes of my question. Thank you
