Since the DSE erases from the current tape position, the WTM ensured that a 3420 wouldn't just run off the end of the reel (not that that's ever happened to me, noooo) when you re-read the tape. But these days you'd just get an EOT indication. I probably would prefix it with a REWIND, however, to ensure that you were at BOT. Alan Altmark z/VM Development IBM Endicott
