Thanks.  But doing so, it expands too late I'm afraid.  What I need is the

\input eplain



\ifx\tempa\tempb yes\else no\fi.


If I process that, I get error.  But, if I put \noexpand just before \refn, as
you suggest, I get `no' whereas the right answer should be `yes'.  Note that,
with old Eplain 2.8.1, I get no error at all unless I cancel
\definexref{label}{\jobname}{} up there.

Please any other suggestion.  Thanks,
