I have read that SB is written in C and is GPL. The oldest date on SourceForge is 2004 but the facebook group states its over 10years old. MSB is written in .NET 3.5 by Microsoft DevLabs. Wikipedia states it originated in 2008. They seem completely unrelated. Is this another Microsoft "Embrace, Extend, and Extinguish" tactic?
I have read that MSB does not allow distribution:
The license is presented when you install the software. Small Basic includes a command line compiler that can be used as part of the product. You may install and use any number of copies of the software on your premises to test how it runs with your programs, distribution is not allowed. Please review the license terms for additional use rights/restrictions. Thank you.
