st: _regress (stata9)

["R.E. De Hoyos" <redeho@hotmail.com>]

I am working under stata9 and I am trying to access the ADO for routine 
_regress, which is the core part of the command "regress". I checked under:

C:\Program Files\Stata9\ado\base\_

but I couldn't find this command, is there a way I can access _regress?

Thanks,
Rafa
