By the way, I wonder whether these are any use to you on ecological | ||
models: | ||

You might be interested in | ||
http://www.j-paine.org/excelsior_2004/intro.html . This is an early | ||
version of my structure-discovery program, to which I gave a | ||
Prolog-TLI-style interface with a command language that could pass | ||
spreadsheets around as values and operate on them. | ||
