Using Stata dynamic tags
========================

I am going to examine fuel efficiency using **auto.dta**. First, I load the dataset:

~~~~
<<dd_do>>
sysuse auto, clear
<</dd_do>>
~~~~

Now I **summarize mpg**, but I only display the output, not the command:

~~~~
<<dd_do: nocommands>>
summarize mpg
<</dd_do>>
~~~~
