It's Pascal, but in literate form with WEB.

I think the Pascal compiler used the PCC back end, but I no longer remember for sure. If so, you might could hook it up to the revived PCC project. Although it sounds like a fun project, there are probably better uses for your time. :-) Arnold ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T476a1d7b83269775-Mc80e8615b718f628a8468339 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
