BUFNO specification - Key = '0034'

DALBUFNO specifies the number of buffers to be assigned to the data control block. It is mutually exclusive with the BUFIN (DALBUFIN), BUFOUT (DALBUFOU), and BUFRQ (DALBUFRQ) keys. When you code DALBUFNO, # and LEN must be one, and PARM contains the number of buffers.

Example: To specify 2 buffers, code: 
KEY   #     LEN   PARM
0034  0001  0001  02
