Probably a reasonably defensible position, too.

Yes, but condition information (eg. SPI RESULT or SQLCODE), needs a
separate statement to row information (eg. ROW_COUNT). ie.
    GET DIAGNOSTICS :a = ROW_COUNT, :c = OID;    GET DIAGNOSTICS EXCEPTION 1 :b = SQLCODE;

but it's not much of a problem, really. And I agree the 'x = y' syntax is
better.

Unfortunately, I don't have an awful lot of free time at the moment, so I
won't be able to look at this for at *least* as week.
