One might be inclined to point you to -preserve- and -restore-, but in your
case it would seem easier to use the -if- qualifier instead of -keep-ing and
-drop-ing.

Subject: st: restoring dataset
Dear Statalisters:
I have a question. After using the command "keep" or "drop" and running
an analysis, how can i ask stata to use all the data again. The problem
starts when I run command e.g. for a subset of years and later I want to
run command on whole years in the same do file again.
Thanks,
Shehzad
