st: MAKTAB for svy estimation

["Wenhhui Wei" <weiwenhui@gmail.com>]

I guess this question is for Nick Winter. 

How can I specify subpop in the MAKTAB syntax? 

For example, when I type 
. mktab (y x1 x2, subpop(elig1)), cmd(svyprobit) log(mylog, replace)

STATA gives an error message, saying 
subpop() invalid
r(198);

Another question is: how do I use XI option in MAKTAB, say, x1 is a
categorical variable, shall I type 

. mktab (y i.x1 x2, subpop(elig1)), cmd(xi: svyprobit) log(mylog, replace)??

Thanks,

Wenhui
