You should have stated, for the record, that -ivreg2- is a
user-written pacakge available from SSC, as per Statalist practice.
Try updating your Stata 8.0 to 8.2 (-update q-) and then see what
happens with -ivreg2-.
Mata was introduced in Stata 9. I suspect that these add-on features
of -ivreg2- that you wish to use are only available from version 9
onwards.
