Open the equation dialog (Quick/Estimate Equation) and specify your model (e.g. y c x1 x2). Then go to the "Options" tab and check the "Heteroskedasticity Consistent Covariance". The default is "White", so when you estimate your equation, standard errors in your output will be computed using "White's Covariance Estimator".
