Hello SUNNERS,

I need some utilities to some tape reading/writing

What am I looking for is:

-  READ/WRITE IBM-MVS partitioned file tapes. 1/2" Reel tapes 
   I bungled with dd which worked partially,
   the problem is when i write a tape with :

     `dd if=infile obs=4000 cbs=80 conv=ebcdic of=/dev/nrmt0`

   I cannot read the tape with obs=4000 on the IBM but it can be read
   with obs=5120 , which in fact is the limit blocksize before a 'LONG TAPE'.
   While reading unformatted tapes back from the IBM on our SUN4/280,
   I can retrieve the files but they seemed to be messed up between tape
   files. I don't know why the IBM looks at the tape as a 5120 blocked tape.

   Also it is rather difficult to retrieve files written on a SUN on a IBM
   made with 'dd'

- READ/WRITE VAX/VMS/RSX FILES-11 Tapes.
   this is very urgent because we do have a lot of VAX/VMS & PDP-11 systems
   Other DEC format tape utils are also  welcome.

Anyone with such beasties in /var/tmp ?? ;-)
