RE: Uncertain on CHAIN vs. SETLL/READE

Happy new year Simon!

Would you care to elaborate on your reply which seems to put some doubt on the other responses to James' post?

I don't have time to go reading up on FIFO, LIFO, FCFO in the DDS and I'm sure that a lot of us would benefit from your reply.

Thanks.

I know that a SETLL with only the leading keyfield, followed by a
READE with that same keyfield, is guaranteed to come back with the
first record with that leading key.

But is that also true of a CHAIN with just the leading keyfield?

The action of both keyed reads will depend on the use of FIFO, LIFO, FCFO in the DDS.
