Swordfish

Swordfish (also known as SF) offers a truly structured and modular approach toward program development - very similar in some respects to if you were programming with Visual Basic or VB.net, but more commonly known as PIC Basic in this form. Not only that, but it produces extremely efficient and stable code. Results are more important then words. Swordfish only supports the 18F range of PIC's, as the older 16F series are very old and have many architectural flaws that inhibit many high end features of a modular compiler. Free version limitations; 200 variables on compile, no program length restrictions.
