Curt, My problem is understanding how to traverse the query. Our dropdown is paginated, we can specify the # of results per paginated drop-down so it being super long or short isn't an issue. The problem is getting the SELECT statements/UniVerse to match what we want the dropdown to do.
For example if I query a table called CLIENT which has @ID indexed, I do the following: EXECUTE 'SELECT CLIENT BY @ID' My questions are: #1) How would I specify 10 results back from the query? #2) How would I 'pick up' where I left off for page 2 (values 11-20)? Doug mentioned using SAVE.LIST to do this, Bill says that you have to do a dance in UniVerse. I guess I'm curious what this dance is that I need to do? If it's not handled in the SELECT then what technique are you using in UniVerse?
