Procedure libraries (PROCLIBs) are data sets that contain JCL procedures and JCL job steps. The procedures include a startup procedure for starting DFSMShsm, a startup procedure for the ABARS secondary address space, and utility jobs for formatting and printing the DFSMShsm logs.

SYS1.PROCLIB is a system library in which the procedures that are included with the DFSMShsm product are placed when you run the starter job. You can create an alternate PROCLIB data set for the startup procedures, the HSMEDIT procedure, and the HSMLOG procedure.
