Note: old PDS limited to 64k tracks, but no limit for member size. > My understanding is that the TTRZ that NOTE returns for a PDS limits the data set and therefore any member to 2^16 tracks. PDSE counts records in 24 bits, so for a sufficiently large LRECL, about 300 bytes, PDSE can hold a larger member than PDS.
