On-Line Missil

MISSIL, a high-level computer language with out-standing data handling capabilities, is described and the use of MISSIL programs in the real-time environment of automatic control is discussed. The MISSIL language and programming system are described, and the interpretive and symbolic aspects of the language are explained. This general description is followed by a discussion of design criteria, language characteristics, and the ways in which MISSIL makes the work of the engineer-turned-programmer both easier and more effective. Finally, a discussion is presented of how MISSIL iS placed into the executive routines of the IBM 1800 process control computer, and several applications are given for which on-line MISSIL has been found highly useful.
