I know you can do that as a crude FSF file, but you can't BSF without CMS. 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. I'll IPL that whenever I need to re-position my main tape drive. <g> Brian Nielsen On Thu, 8 Jun 2006 15:30:11 -0700, Schuh, Richard <[EMAIL PROTECTED]> wrote : >You do not have to use CMS.
