Volume IV begins with the Logic Programming group, all descended from John McCarthy's LISP of the late 1960s. The Volume begins with a few pages from the LISP 1.5 Programmer's Manual, a vital token of things to come and moves on to LISP's offspring: LISP, Scheme, Guile, and CLOS. Finally, Jamie Andrews provides a substantial essay on the most important Functional programming language, Prolog. The contributions are designed to enable the programmer to evaluate the languages and to understand the ways in which each works.* Bob Chassell on Emacs LISP,* Brian Harvey on Scheme,* Jim Blandy on Guile,* Jim Veitch on CLOS,* Jamie Andrews on Prolog.
