Some example Stata code - a code block and the logged note:

```
sysuse auto
generate gpm = 1/mpg
```

`(1978 Automobile Data)`

A continued example - code and log:

`ttest gpm, by(foreign)`

```
Two-sample t test with equal variances

A graph, (cleaned) code with the log hidden:

`graph twoway scatter gpm weight`

The resulting graph:

And some hidden cleanup follows.
