Using generic references

To retrieve the value of the label defined via \definexref (see the previous section), Eplain provides the following macros:

\refn{label}

\xrefn{label}

\refn and \xrefn (they are synonyms) produce the bare definition of label. If label isn't defined, issue a warning, and produce label itself instead, in typewriter. (The warning isn't given if \xrefwarningfalse.)

\ref{label}

Given the class c for label (see the description of \definexref in the previous section), expand the control sequence \c word (if it's defined) followed by a tie. Then call \refn on label. (Example below.)

\refs{label}

Like \ref, but append the letter `s' to the \...word.

The purpose of the \...word macro is to produce the word `Section' or `Figure' or whatever that usually precedes the actual reference number.

Here is an example:

\def\sectionword{Section}
\definexref{sec-intro}{3.1}{section}
\definexref{sec-next}{3.2}{section}
See \refs{sec-intro} and \refn{sec-next} ...

This produces `See Sections 3.1 and 3.2 ...'
