It would be interesting if that can then be reloaded and the inside array recovered OK. Of course, one runs into the danger of overdoing the nesting -- as the user guide says: 'The mutual “packability” of bundles and arrays means that it’s possible to go quite far down the rabbit-hole. . . users are advised not to get carried away.' cheers sven
