 note = {This is the report that presents a process of the improvement of the Operating System in the computer of FACOM 270-20. When we used this computer on it's Batch System, We required some other function, so we analyzed this Operating System by machine language. And to add or to charige this Operating System, we made some system programs in the assembly language (FASP) and some routines in a machine language. Making a system program, we must use the assembly language and make an efficient program. After analyzing this Operating System, we produced a new Operating System. On it's System, we can get some infomation of our program., 長崎大学工学部研究報告, (11), pp.21-28; 1978},
