From: Provan@LLL-MFE.ARPA For those of you (like me) who have to use Bliss or Macro, the way to get sequential files shared properly is to light the UPI bit along with any sharing bits you want. I'm not sure what this is supposed to do from the documentation, but my tests seems to indicate it's like signing an agreement that VMS will try to do what you want, but since you're dealing with a sequential file, it won't take full responsibility. The only "hole" I've found is that you can create a new version of a file that's open but not sharable for writing. Since this won't screw up the data in the log file (since the original writer is still writing into his log file, which is now ;-1), I'll live with this.
