Here are the other footnotes (I should have pasted them near footnote 20):
7) Addresses are cached on the request handle.
9) One shall not free or deallocate the bu er before the operation is freed, that is MPI_REQUEST_FREE returned.
14) Nonblocking procedure without an I pre fix.
=====
I will move PREADY,...,PARRIVED after START... good suggestion.
I also agree with "ic" for the PREADY, PARRIVED procedures.

Hi Puri,
Thanks for this - a great way to provoke some progress (no pun intended).
I would suggest: move the rows dealing with MPI_PREADY and MPI_PARRIVED between MPI_START and MPI_WAIT, i.e. in the approximate calling order.
Also, I would add “ic” for the new MPI_PREADY, MPI_PARRIVED, etc procedures - because the operation is definitely incomplete at the point in time they are called, during the time interval of their entire execution, and at the point in time they return - there is no possibility they could be completing or freeing procedures.
What are the other footnotes: 7, 9, and 14? (I could look them up but I’d have to choose the same draft version as you because the numbering changed recently.)
Cheers,
Dan.
