You can simply program


foreach var of varlist var*{ 
quietly: su `var' , de
replace `var' = (`var' - `r(mean)') / `r(sd)'
}

I need to calculate z-scores for a large number of variables. Does
anyone have a macro/script for z-score calculations of this sort, or
know of an ADO that can do it?  (I'm relatively new to STATA & miss
the ease of the z-score function as part of descriptives in SPSS.)
