Here is an example of what I think you want to do. You want to divide many variables by one variable. In these cases it is sometimes easier to specify the variables you do not want to divide rather than the variables you do want to divide. You can do so with the -not- option in -ds-. -ds- also has other useful shortcuts, that can help you, see -help ds-. After that it is just a matter of storing the returned varlist in a macro, and than loop over the elements of that macro. Below is an example: *---------------- begin example ------------------- sysuse auto, clear // assume that make is your id variable // and weight your scaling variable ds make weight, not local vars "`r(varlist)'" foreach var of local vars { gen sc_`var' = `var' / weight label var sc_`var' "scaled version of `var'" } *---------------- end example -------------------- (For more on examples I sent to the Statalist see: http://www.maartenbuis.nl/example_faq ) Hope this helps, Maarten -------------------------- Maarten L.
