[HECnet] Security hole in CSWS

[Bob Armstrong]

Actually, in VMS (as well as in RSX), ;-1 means the oldest version

I think you only have ;-1 and ;0 which are special.

  Can't speak for RSX's problems, but for VMS none of this is true.

  Give it a try for yourself (there are lots of VMS systems on HECnet!).
