Part I, the allocation section, discusses volume attributes, considerations in allocating direct access storage devices, and the function of dynamic allocation. Dynamic allocation can be invoked through DYNALLOC macro instruction or through dynamic allocation interface routine (DAIR). This publication discusses the DYNALLOC macro instruction and its associated parameter structure, and reference information for the parameter structure. Part II, the JES2 section, describes those aspects of JES2 processing that can be affected during system generation, during system initialization, or by user programming. The discussion is intended to tell the system programmer how he can affect JES2 processing but not to tell him how to code the system generation macro instructions and other initialization parameters. Part III, the miscellaneous job management section, discusses restarting support, assigning special program properties, limiting user region size, changing the system log processing, updating MSTRJCL data set, and the external writer.
