Micro Focus Enterprise Server for .NET provides support for the most commonly used IBM batch utilities. For each supported utility, Micro Focus Enterprise Server for .NET provides a corresponding program (an alias) that emulates the utility's functionality. The aliases used by a region are defined in the region start-up file. The Enterprise Server for .NET Administration UI is used to view these definitions. You can add additional entries to this list, or change existing entries so that your own programs are used instead of the Micro Focus Enterprise Server for .NET defaults.
