For the benefit of future searches of the forum, it would have been better to start this on a new topic. In fact, ideally, each topic would have a title that describes what the topic is, rather than “questions”, so the original title of this topic would have been better as something like “Data Sheet Font”. But, things are never ideal, so no biggie.
In any case, Panorama X has a Group Up command exactly like previous versions of Panorama did, it works the same and can be found in the Analyze submenu of the Field menu.
The Group Up commands have always operated on the entire database, not just selected records. This has been true since Panorama 1.0. There is no way to group only selected records – if you think about it, how could there be, since like sorting, the entire database is rearranged.
You can, however, select a subset before grouping, and only that subset will be visible. This is the same as before.
