No, AFAIK. That would require that the rows be released from the server
one by by one, rather than either being released as the output of the
successfully completed SP or being erased altogether in the case that it
abends...for atomicity, it shouldn't produce a "partial success". It
should either totally succeed or totally fail.

A way you could test that would be to hook up a TIB_Cursor to a SELECT
procedure that works like the posted example, build an exception into one
of the rows it has to process in the loop and see whether you
get any rows back in the TIB_Cursor. You could do it in fact in the Cursor
window of IB_SQL, couldn't you?
