Here is my full problem.
I want to estimate rolling regressions on a firm by firm basis. Then for each regression I want to find the standard deviation of the residuals.
Nick Cox gave you some good advice about using -rollreg-. While I have never used -rollreg-, your problem looks like it might fit into a scheme such as...

levels id, local(idlist)
foreach i of local idlist {
rollreg ... if id==`i'

<plus code to make use of or store the results from each iteration>

I hope this helps.
