   Which was almost interoperable with VMS.  The only problem I had
   passing data between VMS and OS/360 using ANSI tapes was
   that the IBM would always finish with an EOV label, which VMS
   took to mean "go to the next of a multi-volume set". 

   We got around this by writing and EOF over the EOV while mounted
   /foreign, then remounting the tape as labeled.

   I never did try actual multi-volume tapes between the two systems.

   Meanwhile, since we wwere putting the first VAX into a IBM 360 shop,
   the nice folks at DEC gave us a little Fortran program that would
   read and write EBCDIC labeled and unlabeled tapes.
