<h4 class="subsection">12.3.4 Customizing cross-reference subscripts</h4>
<a name="index-Bullet"></a>
<a name="index-Subscript_002c-bullet"></a>
<p>When <small>FWEAVE</small> pretty-prints code, it can attach cross-reference
subscripts to various kinds of identifiers such as function or macro
names. [A bullet
for a subscript indicates that the name was defined in the
current section.]
The actual marking of the cross reference is done by
the command ‘<samp>@[</samp>’ (see <a href="AT_005b.html#AT_005b">AT[</a>). This is usually done
implicitly; for example, the commands ‘<samp>@a</samp>’, ‘<samp>@d</samp>’, and
‘<samp>@m</samp>’ issue an implicit ‘<samp>@[</samp>’. (See the discussion of
‘<samp>@a</samp>’ in <a href="ATa.html#ATa">ATa</a>.) In C, various declarations of
variables also result in such an implicit mark.
</p>
<p>Various nuances in the type (possibly underlined) used for the
subscript give a hint about what kind of identifier <small>FWEAVE</small> thinks
it’s working with. For more information about the typesetting
conventions, see the definition of the
primitive macro ‘<samp>\W@IN</samp>’ in <samp>fwebmac.web</samp>.]
<a name="index-Bullet-subscript"></a>
The following flags select which identifiers are so subscripted.
</p>
<p>To see the default values of these parameters, say ‘<samp>ftangle
-Zmark_defined</samp>’. To turn off the subscripting operations completely, use the
‘<samp>-f</samp>’ option (see <a href="_002df.html#g_t_002df">-f</a>).
