Probably I did not understand all the discussion above, but IMHO there are no size limitations for PDS *or* PDSE.

Re: PDS multi-volume
The traditional limitation to 2^16-1 = 65535 tracks is one more instance of control-block overflow, here that of in an unsigned halfword field. PDS support is 'functionally stabilized', i.e., frozen. For this and other reasons it is thus---with the well-known exceptions of system data sets that must be accessed shortly after an IPL---it is now usually better to use PDSEs.

I would guess directory complexity. And, performance. PKZIP solved it by putting the directory on the last disk. But, unlike PKZIP, too many programmes, and utilities 'know' the format of PDS/PDSE.

But if both the TTRZ and the TTTR are four bytes the change is less disruptive than changing the size of a field. IIRC, one could point to the block after the NOTE by setting the low byte of the TTRZ to 01. Is this facility continued with the low bit of the TTTR?
