What if the file pointer is currently after the first match?

Doesn't matter. CHAIN (with key) uses the file's keyed access path so repositioning occurs. However, that's no guarantee of the first matching record hence my previous response regarding the DDS keywords FIFO, LIFO, and FCFO. The only thing you can be sure of with CHAIN is that (presuming no changes to the file data) the record returned by a given CHAIN is the one that will always be returned by that CHAIN i.e. first match, last match, or first changed match.
