Interesting! When Vertical solftware took over VS Trilogy, they contacted me
and, since I'd built a toolbox for Turbo/PDC Prolog, asked if I'd be willing
to do one for them. I said I'd be willing to consider it and they sent me a
demo but requested that I pay for the end-product. To which I decided a) I
did not want to do business with a company that wasn't willing to make a
reasonable effort and was so hard-up for money that they wanted to charge me
to develop a set of tools for their program, and b) I didn't think the market
was big enough, restricted as the Turbo/PDC Prolog market already was. It's
really too bad because I really liked the C-Prolog combination of Trilogy,
conceptually anyhow...
