Good point... But you'll have to be careful when using -st_local()-.
st_local("test", 1) fails, so you'll have to execute st_local("test",
"1"). But once you have local test in Stata, you can use it as a
numeric fine. In my example before, you could execute something like
st_local("rows", strofreal(rows(X)). Probably better than messing with
scalars...
