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.

He answered half of his question: he wants to use the -restore-  
command. But before doing that he must have the foresight to use - 

sysuse auto
keep if foreign

etc.  Admittedly a silly example, as one could just summarize if  
foreign, but illustrative.

-help preserve-
