Robert, If the application can support it, starting with z/OS 1.7 you can have data sets larger than 65535 tracks per volume.

I found some paragraphs in 'Using Data Sets' which say - multivolume datasets can extend to a maximum of 59 volumes - maximum tracks per volume per dataset: 65535 tracks I didn't find however any remark mentioning maximum size in bytes. Doing the math, at a blocksize of 27648 that would make 2 blocks per track. All in all 59 x 65535 x 2 x 27648 bytes or 213,805,578,240 bytes. Would that be the correct (theoretical) maximum dataset size for a dataset with aforementioned characteristics?
