The JES job information services (SSI function code 71) allows a user-supplied program to obtain information about jobs in the JES queues. Currently only JES2 supports this SSI function code. Most of the information provided via this SSI is very dependent on the version and level of JES2 you are currently running and requires a knowledge of JES2 data structures. Some of the information may be available in a version-independent format using other interfaces (such as SSI 80).
