There are some inherent difficulties in programming operating systems(OSs) in a high level programming language. This is chiefly because an OS program requires close interaction with the hardware on which it runs, while a high level programming language tends to hide the machine structure. In this paper, a model and implementation of a hybrid machine which enables programs to cope with such difficulties is proposed. The model can handle both OSs written in a high level language and job programs in a binary machine code, and it can also provide a good environment for OS programming. An implementation has been used in an educational programming laboratory course in operating systems. Some drawbacks of the model and measures to address such drawbacks are discussed in detail.
