I am switching from running my TOBII studies in Eprime to running them in Inquisit and I am wondering if it is possible to have the experiment script define areas of interest so that the output includes not just x and y coordinates but also which AOI they correspond to. In eprime you can mark objects as AOIs and there are userdefined and AOI columns in the output that tell you what part of the trial is playing and which AOI the participant was looking at.
How would I make Inquisit do that?

Ah, I see. I wasn't clear on what exactly you were planning to do. There are two options:
(1) You should be able to calculate the cumulative viewing time for each object with the approach sketched out at https://www.millisecond.com/forums/FindPost14474.aspx
The respective variables can then be logged to the regular data file (not the gaze file).
(2) You can also do the mapping of gaze points to on-screen objects after the fact using your preferred analysis application. To that end, you would probably want to have Inquisit insert a marker into the gaze data file signifying trial onset as well as have the trials produce screen captures (set / screencapture = true) so you can produce heat-map like overlays of gaze data points / durations over the objects as presented on screen for each respective trial.
