Hi All,

	I know the question has probably been asked (and answered) before
in this group but I couldn't find the answer. So please forgive me for 
wasting the bandwidth.

	I want to assign ONE number to a group of equations and letters to 
the individual equations in the group so that the output will be something 
like (2.1a), (2.1b), (2.1c). When I refer to those equations, I would like 
to be able to refer to the individual euqations, like "Please see Equation (
2.1a)", as well as refer the the group as a whole, such "Please see 
Equation (2.1)".

	My question is is this possible? if yes how can I achieve this? Are 
there .sty file(s) available to do this?

	Thanx very much.
