Maybe it was SAS C, and not Lattice - sounds familiar. Thanks for the link! CanDo could have been a killer app if things were to have gone differently. It was basically the early Amiga equivalent of the later (PC) Delphi (another language I have a lot of experience in, long story) - Eddie Churchill who was a CanDo dev went to work for Borland and contributed to Delphi.. and so history is written, winding its way through our lives. I'm working on getting an old website of mine "CanDo Corral" back up and accessible. Hopefully before summer.
