• Run a series of linear regressions

sysuse auto, clear foreach v of varlist mpg weight-turn {

regress price `v', robust

}

regress price i.foreign local num_obs = e(N) global myglobal = 4

• Generate and manipulate variables

generate newvar1 = “string” generate newvar2 = 34 - ‘num_obs’ replace newvar2 = $myglobal
