Stata Code Fragment: 
Using "for"

* lets start with a tiny file
clear
input id y80 y81
1  5  6
2 10 11
3 15 16
4  3  4
end

* you can use the "for" command to repeat a command over and over
for var y80 y81: summarize X

* The command above acts like you typed
summarize y80
summarize y81

* This is not useful for the summarize command, but it would
* be useful for a command that takes only one variable

* You can also combine this with global variables
global y "y80 y81"
for var $y: summarize X
