More on Extensible Machines One of the most salient characteristics of extensible machines (EM) is the facility for providing system control over program-to-program and program-to-data linkage (e.g., address connection). It is the intent of this paper to expand and clarify the remarks concerning program-to-program and program-to-data linkage that were embodied in the authors' previous paper on the EM concepts, and to, finally, trace the employment of linkage mechanisms through various levels of programming languages.
