Fellow IBM-MAINers,

a question regarding maximum dataset size (for a SAS library where
"SAS library" nowadays uses to be a PS dataset with RECFM=FS and
BLKSIZE=27648) popped up on SAS-L.

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?


TIA
