Asystem design language, DEAPLAN, is described. This language is designed so as to be suitable for use instructured top-down design of the whole operating systems. Some major features that seem to be necessary in such design languages are as follows:(1) ability to define and use any module and/or module type whose logical level is higher than that of a procedure appearing in conventional programming languages, (2) ability to define and use any module whose internal structure is undefined, (3) ability to define and use any data and/or data type whose internal structure is undefined, (4) ability to provide appropriate means for highly efficient structured design, (5) ability to describe storage allocation and interface between modules, Using such a language, it is hoped that we can take a step toward the computer aided design of operating systems.
