It may be that there is a much better up-to-date way of doing
this, but I don't know.
It may be that -stgtcalc- is calling very out-of-date -st-
commands. Slapping -version- on is not going to fix that.
You could -set trace on- and see where the message is coming
from.
Very likely, somebody needs to get inside. Neither Peter nor Patrick
is a member of Statalist. Peter's current details
are
Professor Peter Sasieni PhD
Wolfson Institute of Preventive Medicine (School of Medicine and Dentistry)
http://www.wolfson.qmul.ac.uk/

and if you are lucky he will have a more up-to-date version.
