st: calculating chage in R^2

```Hi All,
I need to run a hierarchical regression (below), but my office is using
STATA 7 and I understand that there is no such command in this version of
STATA.   So, I simply entered my DV followed by the two covariates and
then by the IV, hoping that this would give me the effect above and beyond
the covariates.  I did not get a change in R^2 and was wondering how to
calculate one.
Thanks,
JW
