AHA! That should do it. I'll give it a go today. I'm glad my class code
seems to be okay. Now I have to add a pair of dictionaries to it...8-)

I'll likely be using no more than a half dozen as search/filter terms. But
that still means I'll have to read and search through the entire list at
least once. I'll have to define a search function in the code that can be
called as many times as necessary, and the temp variable will be local to
the function, simply returning a smaller dataset on each pass.

The only time I'll be interested in the total set  of fields is for display.

Thanks
And thanks to Emile and Tjabo, too...
