This seems like dangerous code, to me, so is probably best run in a
throwaway session. That said, I have not experienced any problems
with it.
Anyways, labs written or co-authored by Ken Iverson seem to be:
Arithmetic
Book of Numbers
Coleman (sample topics)
Finite mathematics
Grade 8-7 (Saxon)
Finite Groups
Mathematical Roots of J
Math Tables
Teacher's Aide
(But I keep wishing for a way to do a "safe load" in J -- where
operations could be limited in their scope: no execution of anything
not in COPATH and no execution of foreigns housed in the current
locale that reach outside that locale. There's no way I can think of
for user code to enforce this restriction.)
