The interesting thing about FBSL use of the LCC compiler and their license, is that
many of FBSL's users have requested (begged, plead) for the creators of FBSL to use the Pelles C free compiler (
http://www.smorgasbordet.com/pellesc/ ) which allows for commercial use. From what I've read, the creators of FBSL have fought against this not for technical reasons or because they had to use LCC, but because they simply do
not want to allow the commercial use of FBSL.
Users and creators of BCX Basic compiler (
http://groups.yahoo.com/group/bcx/ ) had the same issue with using LCC, but they were able to get a project going to use Pelles C compiler and thus that programming language could be used for both personal and commercial applications.
Despite the license and various syntax, I do think there is some interesting things about FBSL and they have done a lot in the development of their programming language. FBSL is a great project.
