Happy 28th Birthday to 386-PROLOG

Today, 28th November 2017, is the 28th anniversary of the very first lines of 386 assembler code being written by Brian D Steel, in what was to become the "386-PROLOG" engine, initially released almost exactly a year later as DOS-PROLOG, and then a couple of years after that, as WIN-PROLOG.

To celebrate the "birthday", so soon after the release of version 6.1 of WIN-PROLOG, all those who have ever downloaded our 28-day Free Trial have been sent an email, offering them a special 90-day Free Trial of the entire new system. Please contact us if you have not received the email, but would nonetheless like to take part in the 90-day Free Trial!

Introducing Weblog!

Weblog is the fresh, new toolkit which provides a direct, streamlined way of combining beautifully designed web pages with logical scripts written in Prolog.

Weblog separates the processes of website design and content programming, so that web pages can be created in familiar tools such as DreamWeaver, PhotoShop and Illustrator, independently of the application code which supports them.
