<P>When writing about program code, it is often desirable
to be able to indicate that a particular word or phrase be
typeset in the same manner as the code being discussed. For
example, one might talk about the variable <SAMP>topval</SAMP>
or the procedure <SAMP>stack_pop</SAMP> and wish for them to
be typeset as they are in this sentence. This, of course, is
simple to do using TeX macros, but use of the (more general)
FunnelWeb typesetting directives to do the same work has the
added benefit of keeping the document portable to other
typesetters.
<P>FunnelWeb provides two in-text type modification
constructs: <SAMP>@{...@}</SAMP> and
<SAMP>@/...@/</SAMP> where
... is raw text. The <SAMP>@{...@}</SAMP> construct
sets the enclosed text in the same manner as the text of
macro definitions is set. The <SAMP>@/...@/</SAMP> construct
emphasises its enclosed text in some typesetter-dependent
fashion. Typically the emphasised text is set in italics.
<P>Here is an example of how these constructs might be
used:
<P>
<PRE>
The following procedure @{put_sloth@} writes the
@{sloth@} variable to the output file. Note: @/The output
file must be opened for writing at this point or the program
will crash!@/
</PRE>
