I would like to use the 'svytab' command for a large number of items from a
questionnaire, and run these results for a large number of subpopulations
in my dataset.  This is a survey of high school students, and for each
item, I would like to run a table by sex and grade level.  The
subpopulations are the various school districts in the state.  Using 'macro
shift' I have written a program that will run 'svytab' for each item in the
questionnaire, but I would like to use 'macro shift' at the same time to
run the tables for each school district.

The variables from the questionnaire items are in a local macro called
'quest'.  (local quest q1 q2 q3 q4...).
Each school district is represented by a dichotomous variable, with a '1'
indicating a respondent from within the particular school district, and a
'0' indicating a student from a different school district.  The school
districts are in a local macro called 'district'.  (local district d1 d2 d3
d4....)
The output I want is a set of tables for each school district (subpop).

This is the program I am using to run the tables, without referring to
subpopulations:

program define xtab
   while `1' ~= "" {
    svytab sex `1', row per ci
    svytab grade `1', row per ci
    macro shift
 }
end

The command I use to run all the tables is:
xtab `quest'

So the question is, how do I get this program to run all of the tables for
each of the various subpopulations, without rewriting the program for each
of the subpopulations?

Thanks,
Dan
