st: sequential application of a model to a number of datasets inmanner of foreach var of varlist

["Ben Dwamena" <bdwamena@med.umich.edu>]

Dear Statalisters,
I wish to empirically compare a linear and nonlinear model using
sequentially 12 different datasets. How may I specify a looping
procedure for the datasets in the manner of foreach var of varlist 
x1-x12........instead of writing a do-file for each dataset?
Thanks
