The LOADxx member of SYS1.PARMLIB can be used to specify the master catalog and other information needed to initialize a system. If the master catalog is specified in this member, the operator is not asked to specify a SYSCATxx member during system initialization.

To identify the master catalog in the LOADxx member, use the SYSCAT statement. The following is the format of the SYSCAT statement for the LOADxx member:

Figure 1. The SYSCAT statement for the LOADxx member.

The information following the SYSCAT keyword is the same as that in the SYSCATxx member of SYS1.NUCLEUS. (See Identifying the Master Catalog and Initial Configuration (SYSCATxx) for an explanation of the values.) The high level qualifier of the tape volume catalog is specified with 1 to 8 characters or the default is SYS1. When the system is initialized with SYSP=xx, the tape volume catalog high level qualifier specified in the LOADxx member is activated.

SYSCAT   SYSRES11  SYS1.MASTERA.ICFCAT                                  y
