file extension FB - Gforth Forth blocks file
File extension FB description:
Gforth is a fast and portable implementation of the ANS Forth
language. It works nicely with the Emacs editor, offers some nice
features such as input completion and history, backtraces, a
decompiler and a powerful locals facility, and it even has a
manual. Gforth combines traditional implementation techniques with
newer techniques for portability and performance: its inner
interpreter is direct threaded with several optimizations, but you can
also use a traditional-style indirect threaded interpreter. Gforth is
distributed under the GNU General Public license (see COPYING).
Gforth runs under GNU, BSD, and similar systems, MS Windows, MacOS X,
OS/2, and DOS and should not be hard to port to other systems
supported by GCC.
