Thanks Joseph for pointing me to the "listcoef" command which is based on Long's regression models
for categorical and limited dependent variables. The package spostado (not part of STATA 8 basic
install) is made available at www.indiana.edu/~jslsoc/spost.htm.

One of the many postestimation commands from J. Scott Long and Jeremy Freese
might work for you here. I've illustrated one of them, -listcoef-, in the
do file below, although I'm not certain that it's what you're looking for.
