CHAIN not found and subsequent READ - docs wrong?

Y'all

The ILE RPG Reference has this to say about a CHAIN that does not complete -

"When the CHAIN operation is not completed successfully (for example, an error occurs or no record is found), the file specified in name must be repositioned (for example, by a CHAIN or SETLL operation) before a subsequent read operation can be done on that file."

Now I've seen that when record-not-found happens, that I can do a READ without repositioning, no problem. Here's the scenario -

READ keyedfile fileds;

CHAIN somekey keyedfile fileds; (%found(keyedfile) = *OFF)

READ keyedfile fileds;


The 2nd READ returns the record that follows the one returned by the first READ - so the READ continues from where things were before the failed CHAIN.

That seems NOT to be how the documentation says it should work - I did not have to do another successful CHAIN or SETLL - "successful" is my word added as my assumption.

Confirm or deny, anyone?
