In UniVerse and UniData you can retrieve a specified set of record IDs, saving them as an active select list. You can either use the active select list immediately in a program or command, or give it a name and save it for future use. A UniVerse session can have up to 11 select lists active at the same time, numbered from 0 through 10. A UniData session can have up to 10 active select lists, numbered from 0 through 9.
