Member name specification - Key = '0003'

DALMEMBR specifies that a particular member of a data set is to be allocated, rather than the entire data set. If the member does not exist and DISP=OLD or DISP=SHR is specified, the allocation will succeed but the job will fail when the data set is opened for input. If the member does not exist and the data set is opened for output, the system will add the member to the data set. The data set member name can contain system symbols. See the information on using system symbols in z/OS MVS Initialization and Tuning Reference for more information. A relative generation group number may be specified as the member name.

When you specify DALMEMBR, you must also specify the dsname key (DALDSNAM). The QNAME (DALQNAME) and IPLTXTID (DALIPLTX) keys are mutually exclusive with DALMEMBR. When you code this key, # must be one, LEN is the actual length of the member name, and PARM contains the member name.

Example: To specify the member name MEM1, code:

KEY    #      LEN     PARM
0003   0001   0004    D4 C5 D4 F1

Example: To specify the relative generation number +1, code:

KEY    #      LEN     PARM
0003   0001   0002    4E F1
