Is there a way that I can do this with one command and not do it for each variable since I have around 40 and that would take a lot of time. Still I dont have to scale all of them by total assets. The company (gvkey) and industry specifications for example should stay unchanged.

You can loop over variables, see -help foreach-. The trick is than is
to create a macro containing the appropriate variables, and feed that
macro to -foreach-. For the creation of that macro I often use -ds-.

Hope this helps,
