Dijkstra's note in the March 1968
<i class="citetitle">Communications of the ACM</i>, <i class="citetitle">Goto Statement
Considered Harmful</i>, fired the first salvo in the structured
programming wars (text at <a href="http://www.acm.org/classics/" target="_top">http://www.acm.org/classics/</a>).
As it <a href="http://www.theregister.co.uk/content/4/26585.html" target="_top"> turns
out</a>, the title under which the letter appeared was actually
supplied by CACM's editor, Niklaus Wirth. Amusingly, the ACM considered
the resulting acrimony sufficiently harmful that it will (by policy) no
longer print an article taking so assertive a position against a coding
practice. (Years afterwards, a contrary view was uttered in a CACM letter
called, inevitably, <i class="citetitle">&#8216;Goto considered harmful&#8217;
considered harmful'</i>'. In the ensuing decades, a large number
of both serious papers and parodies have borne titles of the form
<i class="citetitle">X considered Y</i>. The structured-programming wars
eventually blew over with the realization that both sides were wrong, but
use of such titles has remained as a persistent minor in-joke (the
&#8216;considered silly&#8217; found at various places in this lexicon is
related).</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="cons.html">Prev</a><EFBFBD></td><td width="20%" align="center"><a accesskey="u" href="../C.html">Up</a></td><td width="40%" align="right"><EFBFBD><a accesskey="n" href="console.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">cons<EFBFBD></td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"><EFBFBD>console</td></tr></table></div></body></html>
