Automated way to extract NM output

Dear NMusers, I wish to run a $EST NM.ctl with 500 $PROBLEMs. Is there an automated way to extract the 500 sets of thetas, omegas, sigmas, and minimization statuses from the single output that NONMEM provides? Two related questions are: a) What is the machinery that runs behind WFN for extracting output after nmbs and b) Xpose31() extracts only a single set (I think it is the first set); will downloading the newer version of Xpose solve this problem? Kindly advice...Mahesh
