Hi,

I would like to be able to use equation numbers for several equations
and also align these at a given point using SMFF in DCF.  For example,
suppose I wanted to output the equations below, more or less as
displayed.

                  --
      w + x + y - >  z = a + b + c + d                  (T.1)
                  --

                  --
                - >  z = a + b + c + d - w - x - y      (T.2)
                  --


                  --
                  >  z = w + x + y - ( a + b + c + d )  (T.3)
                  --

Using something like

  :df align=left. eqno (T.1)
    <w %% + %% x %% + %% y %% - sum of z here = ...> hvabove
    <                         - sum of z here = ...> hvabove
    <                           sum of z here = ...>
  :edf.

will make alignment easy, but will only allow a single equation number,
while using something like
.se sp2 = '                   '
.se sp3 = '                       '
  :df align=left. eqno (T.1)
    <w %% + %% x %% + %% y %% - sum of z here = ...>
  :edf.
  :df align=left. eqno (T.2)
    <sp2                      - sum of z here = ...>
  :edf.
  :df align=left. eqno (T.3)
    <sp3                        sum of z here = ...>
  :edf.

works if &sp2 and &sp3 are set right, but requires finding the
values for these variables.  Does anyone know a better way to do
this?  Thanks in advance for any info.
