For me, its just the performer name and just to the stage, not to the side of the stage (Mr./Ms. Smith to stage please). For coro/supers, its usually just paging the group to the stage, as choruses in opera tend to follow the same track, or its broken into male/female/childrens coro. If, for instance, one member (or a small group) of coro or supers appears separately from the rest of the group, I would call them by name. As an ASM, around the 2 minute to entrance mark, if the performers I need are not present I ask for a re-page, and then as the stage manager, I would probably include the side of the stage in my re-page, and if it were specific coro or supers missing, they would get a page by name if possible.
