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.
