[HECnet] VMS progtram for real tape -> TAP --> VMS copying through clustering --> tenvax rtc

[Mark Pizzolato - Info Comm]

Why would that matter?  However Glen’s program manages to do it, it is the only thing that should care about that detail since it will be writing the RMS file and then reading it when outputting to the physical tape.

How does RMS format encode tape marks?

You could use Glen Everhardt’s program to read the physical tape and store it locally in RMS format.  Then you could move the RMS file across your cluster environment (or access it directly) on a sim VAX to write to a simh simulated tape drive.  The file attached to the simh VAX simulated tape drive will be in simh format and will be readable just find on a simh KS10.

  There's also a VMSTPCE program by Glen Everhardt that dumps magtapes to disk container files and back again, but it uses RMS variable length record files for its container.  Each file record is one tape record.  Not simh compatible, although I could write a program to convert to tap format.
