Good catch - it should be "control variables with the same name and performance variables with the same name and class". I think the rest fits, but it would be good to double check (I only have it on my cell right now).<br>

Yes. What do others think about this?<br>
<br>
NOTE: We have about 3.5 hours to get this right/done/sent to the mpi-forum list. (or defer to the next meeting). I.e., T-2 weeks to the meeting is at 2pm US Central time today.<br>
<br>
The only thing I might change is from "...return the same string OUT parameters..." to "...return the same string valued OUT parameters..." This is the canonical issue that we don't care what the value of the (char*) pointer is; we care that the *string value*
itself is what is the same.<br>
