You can manually BSF all the way to load point - it was called a Rewind button in the olden days :). I think there is a different name on the button nowadays; however, I can't be sure because the machine room is over 1000 miles away.

A CP command to FSF would be much faster and cleaner than multiple = IPL's. CP already provides REWIND, so a command to do FSF and BSF isn't much of = a stretch. Maybe I'll write an IPL'able utility that will issue FSF and BSF commands= to a tape drive.
