|
|
is no heading at all. The use of "p" was a little confusing, and went back
|
|
to CWEB, which used the term "paragraph" differently from us: it was "p"
|

short for what CWEB called a "paragraph". We now use <code class="display"><span class="extract">@h</span></code> or equivalently

<code class="display"><span class="extract">@heading</span></code> for a heading.
