WARNINGS
The graphics mode (plot ...) is not particularly useful unless the
tplot command is available on your
system.
bs is not tolerant of some errors. For example, mistyping a
fun declaration is difficult to correct
because a new definition cannot be made without doing a
clear. The best solution in such a case is to
start by using the edit command.
