Mathematica Packages and other programs
by Charles Wells

CELLAUT.BAS is a QuickBasic program that implements the "industrious ant", a cellular automaton. It is documented in comments in the program. This file is an ordinary text file.
CFG.MA is a preliminary version (it works, though) of a Mathematica notebook containing code that reads in a string and a context-free grammar and determines if the string is in the language defined by the grammar.
RIEMANN.M is a Mathematica package that provides commands to show graphically a Riemann sum associated to a function defined on an interval. It is documented briefly in RIEMANN.DOC. The notebook RIEMEXAM.MA. provides a few examples.
DMFUNCS.M This is a small package of functions for discrete mathematics and logic. It is documented in comments in the file.
