The rapid spontaneous growth of the IBM Corporate Job Network is probably attributable to the design philosophy employed by its software support. The lack of dependence on uncommon computer machinery and VM/370 hypervisor modifications, the ease of installation requiring no system generation or unusual virtual machine specification, the familiarity of the operator command language and procedures for subsystem loading and maintenance, the relative operational independence afforded by the peer relationship of the interconnected systems, and the simplicity of the user interface have encouraged computer installations to invest some effort to give VNET a trial. The simulated unit-record device interface affords operating systems running under VM/370 some access to the network without any software modifications at all. Initial experiences with an unfamiliar computer system interface appear to generate strong lasting effects. A crucial factor in the success or failure of new system software is its cooperativeness with naive users.
