<P><FONT SIZE="5">4.3 Free Text</FONT><BR>
<P><STRONG>Free text</STRONG> is any text that is not part
of a macro definition or a directive. A scrap of free text
consists of a sequence of items drawn from the following
list: non-special printable characters, insert-eol special
sequences, insert special character special sequences,
insert arbitrary character special sequence.
<P>
<PRE>
free_text = ordinary_text
ordinary_text = { ordinary_char | eol | text_special }+
text_special = "@+" | "@@" | "@^" char_spec
ordinary_char = " ".."~" - special
</PRE>
<P>An example of some rather messy free text is as
follows:
<PRE>
This@@ is a very@+ messy
@^D(009)chunk of text indeed.
But FunnelWeb still views it as
a single chunk of text.
</PRE>
<P>FunnelWeb never sees two text chunks next to each other
in the input; they are always merged into a single text
token.
<P>The free text in an input file does not affect the
product files. However, by default, it appears in the
printed documentation exactly as it is given in the input
file, except that it is filled and justified into
paragraphs.
<P>Any printable character or particular sequence of
characters may appear in the free text of a document.
FunnelWeb ensures that they will appear exactly as given in
the input file, even if they happen to be escape characters
or commands in the target typesetter. However, FunnelWeb
also provides a special mode that allows this censoring to
be overridden.
