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. Tim Liao ---- Original message ----

Hi! I wonder if anyone has experiences of calling other

I don't know what LEM is. If it's a language that can
produce DLLs or
.so's, then it should be straightforward to call them.
If it's a
program using standard input and output, the system()
function is what
you want.
Nor do, I, but my guess is that it is the program referred
to at
#LEM
Perhaps Tim F Liao can enlighten us. -- Brian D. Ripley, ripley at stats.ox.ac.uk Professor of Applied Statistics,
