Please forgive me if this is a simple question but I am relatively new to STATA.  

Is it possible in STATA to have several datasets that automatically feed and update another one.  I.e If i were to have the populations of all the towns in a certain county in seperate datasets, would it be possible to feed this data into a county dataset which would automatically update itself if I were to change the population of one of the towns.  

Also I am embarking upon writing several do-files and with only a basic C++ programming experience would like to know if there is a command that allows me to enter variables into a running do-file.  For example in a certain do-file, i can run it for males or females.  What would i do to have stata prompt me with the question 'which sex would you like to use' and then my response being recognised as the answer.
