$PRGNAM: $PRGNAM (programming language)
$PRGNAM:
$PRGNAM: Gforth is a fast and portable implementation of the ANS Forth language.
$PRGNAM: It works nicely with the Emacs editor, offers some nice features such as
$PRGNAM: input completion and history and a powerful locals facility, and it even
$PRGNAM: has (the beginnings of) a manual. Gforth employs traditional implementation
$PRGNAM: techniques: its inner interpreter is indirect or direct threaded.
