Thanks for the pointer, Ed, but I can't use SMB because I am not dealing with Extended datasets. As noted in the info you quoted below, the requirements to use SMB include a requirement to use SMS storage and Extended format.
I am using SMS storage but not Extended format here. At the moment Extended format requires a special request to the storage admins, and so is rarely used.
