The Network Job Entry Facility for JESZ provides a simple yet powerful means of connecting computer systems together. It allowed a user to move into application-to-application networking even before the availability of this type of support in SNA. It is easy to install: system programmers who are familiar with the non-networking versions of JES2 (Releases 4.0 and 4.1) will find that moving to the NJE facility is not a large step. In conjunction with NJI, NJE allows job networks to be built from computers running four different types of operating systems and job entry subsystems; this type of network can be both a migration aid and a powerful interconnection between interactive systems (such as VMl370) and batch systems (such as MVS). Finally, NJE provides a clear-cut and easy-to-use migration path from BSC networking to SNA.
