I neglected to forward the answer on this to the MathGroup until now.

Thus, there seems to be no way to have automatic numbering (and, say, cross referencing) of equations that are aligned. -- http://chris.chiasson.name/ ________________________________________________________________________ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Chris, The response I have gotten indicate that this sort of alignment is not yet possible. I am told that the closest implementation is in Publicon, but that it is unlikely to work outside of Publicon. This is known and has been reported.
