Thanks to both Duncan Murdoch and Brian Ripley. LEM indeed
is the program that Brian referred to in his response, a
program for latent class/trait loglinear and event history
analysis compiled with Borland Pascal. There's a dos
version and a windows version. Not sure the program will
produce dll's, but I'll do a bit exploration and report back.
