Thanks for the suggestion. That means I can handle the existing stuff as
a special case (no sublists). 

I've not been able to afford a copy of Mathmatica (impoverished, retired,

of what it provided.

If anyone can supply more info on what Mathmatica can do in this area
it would be appreciated....
