Dsname specification - Key = '0002'

DALDSNAM specifies the name of the data set to be allocated. The data set name can contain special characters, if the data set name is enclosed in apostrophes. The system cannot catalog a data set name enclosed in apostrophes; it will use a disposition of KEEP instead. The data set name can contain system symbols. See the information on using system symbols in z/OS MVS Initialization and Tuning Reference for more information.

Dynamic allocation does not support backward references. See Table 1.

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

The maximum length of the data set name is 44 characters, excluding any enclosing apostrophes and compressing any double apostrophes within the data set name.

Example: To specify the dsname MYDATA, code:

KEY    #      LEN    PARM
0002   0001   0006   D4 E8 C4 C1 E3 C1

Example: To specify the temporary dsname &LOAD, code:

KEY    #      LEN    PARM
0002   0001   0005   50 D3 D6 C1 C4

Example: To specify the dsname A.B, code:

KEY    #      LEN    PARM
0002   0001   0003   C1 4B C2
