Awesome ... the +Val also has the good sideeffect that the UI is
updated to upper case :)
It's wonderful to gather these PicoLisp nuggets of wisdom!!! Thanks Alex.

Ah, and of course +ListTextField already returns a list of strings, so the

Ah, yes, sure! A valid solution!
I just did not trigger on that pattern, because I use (filter prog Lst), or

Oh! ... now I see the spacing problem .. sorry about that, I think it must
be the result of copying from the terminal and pasting.
The last proposal was perfect - indeed it works just fine for tags (I've
tried different pasting this time).

I do not understand your intention. I thougt you wanted an AND of all tags, so
the @Gen generator was obsolete.
My last proposal was:

Sure, I'll do a pp in future - also start following that conventions.
About @Gen using @Names - the second argument of mapcan in the definition
of @Gen is essentially @Names. I am looking for a way to avoid having to

Could you in the future provide code which is formatted in a more readable way?
It is very hard to decipher. Better no spaces between lines,

I'll need a little bit more help with Pilog in QueryChart - In the code

Yes, exactly. And it is faster than pure Pilog ;)
