Keith, this is probably one for support. "gweight" is an option in
the ado file which handles prefix commands like "svy:".
A few things for your colleague to do:
1. Update Stata 9 to the latest version.
2. Run -svydes- and check that the data look right
3. Run some other -svy- commands. -svy: mean- should give the same
result as -svy: prop-.

I'm posting this question from a colleague, because I don't know
the answer.
--------------
The gastro survey done in 2002 had weights attached and I used STATA 8
'svy' commands to do procedures which worked fine. However, the change
in version has meant there is a new syntax for invoking the svy
procedures and I can't get it to work. Would you be able to help with
this please?
I have run the svyset command which seems to go OK
svyset [pweight=newwt], strata(statenum) vce(linearized)
pweight: newwt
VCE: linearized
Strata 1: statenum
SU 1: <observations>
FPC 1: <zero>
Then I try a procedure like 'proportions' and get the following error
message about 'option gweight not allowed'
svy: proportion respdefn
option gweight not allowed
r(198);
Are you able to shed any light on this please? (also I am not sure
what
gweight is compared to the pweight in the svyset command.)
