MDSS, A Real-Time Problem-Oriented Programming System with Conversational Tuning Facilities
MDSS, MELCOM DDC & SUPERVISORY-CONTROL SYSTEM, is a comprehensive operating system with a problem-oriented language, developed for improving conventional procedural programming languages like FORTRAN in the aspects of compact description of process data monitoring and execution control of program tasks, and program documentation.
The language consists of descriptions of process data and associated manipulations written in format-defined manner, declarations of variables and program structure, and descriptions of control loops corresponding to the functional units in conventional block diagrams.
At the run-time, MDSS works as a multi-task operating system with an extended priority control mechanism under control of a directing routine which interpretes the object program parameters and activates the calling sequences connecting to the corresponding algorithm packages. MDSS has a set of system tuning facilities which enables modifications on programs or data in conversational mode in the source language level.
