Pixie Scheme implements the "Scheme" dialect of Lisp, as defined in "Revised3 Report on the Algorithmic Language Scheme". Pixie Scheme lacks some of R3 Scheme's numeric types, and omits a few of its syntactic esoterica. It has only a simple compiler, no fancy builtΓÇôin editor, and no support for the majority of the special Macintosh features found in the Toolbox.
This HyperCard stack is NOT a tutorial for Scheme in general; it is merely a guide to this implementation. If you don't already know some Lisp or Scheme, this stack won't help you much.
