equation numbering: subfurmulas

equation numbering: subfurmulas

[Mojca Miklavec]

I took the following document as a source:
    http://wiki.contextgarden.net/images/b/b4/Mathalign.pdf
(Btw: Aditya, why isn't the latest version also on
http://dl.contextgarden.net/myway/mathalign.pdf?)

Section 4.2 says one thing and does the other ...

I want to have my equations numbered as
  a_1 = (1,0,0)    (1a)
  a_2 = (0,1,0)    (1b)
  a_3 = (0,0,1)    (1c)
and then reference them as equation (1).

The example from Aditya's document says the following:

\placesubformula
\startformula \startalign
\NC a_1 x + b_1 y \NC = c_1 \NR[+][a]
\NC a_2 x + b_2 y \NC = c_2 \NR[+][b]
\stopalign \stopformula

But if I try that in MKII, I get (0a) and (0b), while if I try that in
MKIV, I get (1) and (2). How do I get (1a) and (1b) with both MKII and
MKIV?

Mojca

(I'm asking about MKII since I have a completely different problem
with every new MKIV version released and I really need to finish that
document even if MKIV crashes or a nuclear war starts ... :) :) :)

Indeed. I just downloaded the 30 May 2010 version of Mathalign.pdf
from the link you provided and visual inspection of the section 4.2
reveals no subformula equation labels in the examples. All tags are
numbered from (10) to (28) and non is in the form of  (1a). It seems
that subformulas did not work for the author either.
