Editorial Reviews

Baf's Guide

An introductory course in the Scheme programming language (a dialect of Lisp) presented as a text adventure - or, to put it another way, a Scheme interpreter with a wee scrap of text adventure wrapped around it. Since it's Z-code, and the first Z-code games were written in another Lisp variant, there's an odd circularity to it all. Not all of Scheme's syntax is represented, but it's still a good show-off piece. Hardly interactive fiction, though.

-- Carl Muckenhoupt

Although "Lists" barely scratches the surface of Scheme's capabilities, I was surprised by how much functionality was crammed into such a small program, particularly with the ease-of-use features. Even if you complete all of the sample exercises within the two-hour time limit, there's plenty more to come back and investigate afterwards.
-- C.E. Forman

An interactive LisP programming tutorial made into an IF piece, September 18, 2015
by mjhayes (Niagara Falls, NY)
Programming tutorials tend to be boring, but not this time. First, play a few rounds of classic IF to wake a genie, and then he will decide to play the role of a teacher.

Internally, there isn't much to this piece, which is why the file size is relatively small. But trying your hand at introductory LisP programming and then having an NPC check the results each step of the way makes it surprisingly fun.
