"The large block interface (LBI) lets your program handle much larger blocks with BSAM or QSAM.
On the current level of the system you can use LBI with BSAM, BPAM, and QSAM for any kind of data set except unit record or a TSO/E terminal. Currently blocks of more than 32 760 bytes are supported only on tape, dummy data sets, and BSAM UNIX files."
