A name within a module capable of being externally referenced, preceded by a period (.), and optionally preceded by a name by which the module is known. An entry name is the symbolic address of an entry point into the module; for example, a CSECT name. A module name can be the name or alias of a load module or the name of an object module. Module or entry names can be any combination of up to eight alphameric characters, the first of which is alphabetic or national.
