Serge Goldstein (the author of the original TRACK) had a utility called Follow. http://www2.marist.edu/~vmshare/browse?fn=FOLLOW&ft=MEMO Looks like my copy got lost in a recent DASD upgrade, and I can't find one on the web anywhere, but maybe this will trigger someone else's memory. Obviously, as described above it wouldn't work on a modern VM system, but it would be a starting point. I used it a couple times, and it helped diagnose a problem in MVS. /ahw
