Thomas:

Thanks for the suggestion.  Clarify is definitely my friend and I use it
all the time.  However, in this case I have a model with robust standard
errors and a cluster option defined.  Clarify will not estimate a model
with these specifications (well... it estimates it but does not use robust
SEs or clustering).  Do you know of a way to use these options in
Clarify???   If so, I would be MOST grateful for the enlightenment.

Thanks a bunch!

-Jennifer
