While waiting for the updates, you might have a try with mac curve fit,
shareware by Kevin Raner. That (current v1.2.2) does multiple simultaneous
fits of any function you throw at it. A function can have up to 8
arguments and you can specify the function by just typing it in the
function window. As it sais: _mac_ curve fit. Requires system 7 and runs
happily with 512 KB of free memory.
