[23] Automatic referencing in documentation sections?

To produce the woven output

For info on porting, see section 5

As Steve Avery reported, you can cheat and, somewhere after you start the module, just throw in something like `\let\refporting=\modno' and then reference it by `see section~\refporting'.

In FWEB, `\modno' is set to the number of the module being typeset.

Another way to refer to a section is described in [M-20.7.18]:

@ Porting.
\modlabel{PORTING}


... more ...


@ Another section.

\modlabel{ANOTHER}


For info on Porting, see \WEBsection{PORTING}.

`section' is inserted automagically. In the same fashion, the label `ANOTHER' allows the user to refer to that section number.

In LaTeX, forward referencing works, in Plain TeX it doesn't. Unless you're using LaTeX, the latter recipe requires that `\modlabel{ANOTHER}' is defined before referring to it.

If you want to say module instead of section, use `\WEBmodule' (or equivalently `\module') instead of `\WEBsection'.
