I think that you are asking about the data per connection that shows current program name and line#?
This is available if you enable the "client statement cache". There are two ways to do that when using ProTop, the * command will turn it on globally (use with caution) and the # command will allow you to specify a specific user.
Or you can enable it directly via PROMON.
Caution: in some situations (mostly old releases) there are memory leaks, permissions problems and potential conflicts that can cause issues if you use this feature carelessly. (To be clear, these are Progress issues -- not ProTop issues.) It can also have a noticeable impact on performance -- especially client/server performance. I do not generally suggest that people turn it on for all users and leave it on permanently (although I know of people who do that successfully). I recommend that you use it when you are looking for a specific problem.
I also suggest that when you turn it on you should almost always use the "single (top of stack)" option. You probably don't really need the full stack and enabling the full stack greatly increases the amount of data collected. Which amplifies the chances for the potential problems described above.
