Rodwan should type the following within Stata to check on the current state of
the Stata 9.2 executable and ado-files.

	. update query

Based on Rodwan's reported error message, it appears that Rodwan's Stata 9.2
executable is not fully up-to-date.  The remedy for this is to run the
following Stata commands:

	. update all
	. update swap


For those interested, the update on 31july2006 contained the addition of the
-gweight- option to the -_parse- command.  -_parse- is used by the parsing
engine employed by the -bootstrap- and -jackknife- prefix commands, which are
called when the -vce(bootstrap)- and -vce(jackknife)- options are specified.
