st: Overwritten?

["Francis, Richard N" <rnfrancis@utep.edu>]

Nick,

I asked the author of the user-written program -sroot- to kindly make a revision to his program, but he declined.

Previously, you suggested that I "would need to -save- the dataset you create each time and then -append- them all."

I included your previous message in part below to help refresh your memory:

My question is this: within the loop below, how would I go about saving the datasets each time?

forval i = 1/`limit' {
         display "Iteration of `i' of `limit"
         replace which = "`: label (id) `i''" in `i'
         srootfix fcf if id == `i' , residuals(rez)
         qui foreach v in Z14 Z24 Z34 Z4t Z3t Z2t Z1t {
                replace `v' = r(`v') in `i'
         }
}

I think I can merge the resulting datasets, just no clue how to save them within a loop.

Grateful for any direction you may suggest.

Thank  you,

Rick
