Referencing an align environment

Referencing an align environment

[David Arnold]

All,

I tried:

\placeformula[eq:twosolve]
\startformula
   \startalign[m=3]
     3-2x&>-1 &&\qor& 3-2x&<1\\
      -2x&>-4 &&&      -2x&<-2\\
        x&<2  &&&        x&>1
   \stopalign
\stopformula

As we see in (\in[eq;twosolve]), ...

But that didn't work.

Suggestions?

There are three equations, which one do you want to refer using 
eq:twosolve? You need to refer each equation explicitly. Something 
like
\placeformula \startformula \startalign[m=3]
  \NC 3 -2x \NC> -1 \NC\NC \qor \NC 3-2x \NC 1 \NR[eq:twosolve]
  \NC -2x \NC -4 \NC\NC\NC -2x \NC< -2 \NR
\stopalign \stopformula

Also note that if you use ams style &.. \\ you need to put \\ on the 
last one also.

Aditya,

I want to reference the whole block, not any one equation.

Thanks.

I do not understand how would you want the output to look like?

  a = b  (1)
  c = d  (2)
  e = f  (3)

As seen in (1),(2) and (3).

Maybe ask Hans for a feature request :-)
