I have tried both Load("filename") and LoadDta("filename", 1, 1, 1) and
they give me the same result. What I find really strange is that I have
used Load() in the past to load Stata data, and I never noticed any
problems, although I think I had at that time the previous version of Ox
and DPD. I have tried re-installing Ox on my new computer to no avail. Any
other suggestions?
BTW, I have a more general question about etiquette. When I respond to an
answer that was given to one of my questions in such a users discussion
list, should I only send my response to the discussion list, or also
directly to the author of the answer?
Thanks in advance,
g
