The following exchange took place on comp.text.tex:

It seems an unusual feature to be missing from eplain.
It seems as simple as changing whether \eqno or \leqno
is performed by \@eqdef.

Perhaps eplain needs a replacement for \eqno/\leqno
(\eqnum?) that would respond to a switch:


Amstex has a similar switch for its \tag macro. Such a feature
would probably be a useful addition to eplain. Or am I missing
