As of December 1, 2020, Focal Point is retired and repurposed as a reference repository. We value the wealth of knowledge that's been shared here over the years. You'll continue to have access to this treasure trove of knowledge, for search purposes only.
New TIBCO Community Coming Soon
In early summer, TIBCO plans to launch a new community—with a new user experience, enhanced search, and expanded capabilities for member engagement with answers and discussions! In advance of that, the current myibi community will be retired on April 30. We will continue to provide updates here on both the retirement of myibi and the new community launch.
What You Need to Know about Our New Community
We value the wealth of knowledge and engagement shared by community members and hope the new community will continue cultivating networking, knowledge sharing, and discussion.
During the transition period, from April 20th until the new community is launched this summer, myibi users should access the TIBCO WebFOCUS page to engage.
I am looking for a keyword that will let me grab the value of the next row to use in a calculation in the current row. There is already a keyword for the last row but I can't seem to find it after looking through documentation. We would like to avoid using hold files at all.
TABLE FILE CAR SUM DEALER_COST COMPUTE TEST/D12 = DEALER_COST + LAST DEALEAR_COST; AS TEST -*COMPUTE TEST2/D12 = NEXT DEALER_COST - DEALER_COST; AS TEST2 BY CAR END
Please let me know if this is something possible in version 8.

As far as I know there is no NEXT row. But using the LAST should be possible, it's just a question of processing where you should only have to "invert" your logic.
It is a question of "did I skiped the fence already and have to look behind or will I skip and look after". According to me, it's easier to know what has happened then knowing what is going to happen...
So I'm pretty sure that is feasible with LAST.

There is no NEXT logic. Use of NEXT or LAST logic implies that a time component is either implied or is an explicit part of the order of the data. Just reverse that so the most recent rows are first then you can use LAST. I do it all the time.
