There's a ContinuationSystem class to do exactly that. I think John Peterson is the only expert with it; we'll see if he chimes in. If you want to add an additional scalar equation, coupled to all the others, by hand, then the SCALAR variable type is now the best way to do that. --- Roy ------------------------------------------------------------------------------ Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.
