The only thing I could come up with is from a RedBook titled DFSMS Release 10 Technical Update which says
Quote:
2.2.5.6 Buffer pool management
When using QSAM to process large tape block sizes, you must let the system build the buffer pool automatically during OPEN. You cannot use the GETPOOL, BUILD, or BUILDRCD macros to build a buffer pool for block sizes, as these macros cannot build buffers which can hold block sizes greater than 32,760. If, during OPEN, the system finds that the DCB contains the address of a buffer control block, and that the buffer length is smaller than the data set block size, you will get the error message IEC141I 013-4C. When you issue CLOSE, the system frees the buffer pool built by OPEN. So you do not have to worry about issuing the FREEPOOL macro in cases where your application needs to repeat OPEN and CLOSE frequently.
When using BSAM to process large tape block sizes, we recommend that you allocate data areas or buffers via GETMAIN, STORAGE, or CPOOL, and do not request them to be allocated by the system during OPEN. When you specify a non-zero BUFNO parameter in DCB to have the system build buffer pool during OPEN, BUFL must be zero. You will get the error message IEC141I 013-4C if you supply a non-zero BUFNO and a non-zero BUFL, and the resulting block size is less than the block size you specified through DCB or DCBE.
