I am struggling with a short programme to create a file of different
cross-tabulations. Here's the program and the corresponding output using
auto.dta
program hrh
version 8.0
tempname sim
postfile `sim' str20 matcell using results, replace
tab `1' `2', matcell(matcell)
post `sim' (matcell)
postclose `sim'
end
***************************************************************************

I would greatly appreciate any help to what is going wrong!! Also what must
I add to an ado program to make a running session of stata acknowledge the

Many thanks.
