Message
Each error message is temporary (see p. 38), so
continuation. Any other key pressed will erase it as well, but will also execute with the
stack contents present. Thus, another easy and safe return to the display shown before
the error occurred is pressing an arbitrary prefix twice.
A final note about flag D: if it is set, errors 4 and 5 will not occur at all, and error 1 will
happen less frequently, since ±∞ and NaN are legal results then (see the respective entry
in CONST and the very end of Appendix B).
