Features
A critical review of recent efforts to automate the writing of translators of programming languages is presented. The formal study of syntax and its application to translator writing are discussed in Section II. Various approaches to automating the postsyntactic (semantic) aspects of translator writing are discussed in Section III, and several related topics in Section IV.
Operating Systems: Program overlay techniques
The general features of program overlay systems are described. Three main types—automatic, semiautomatic and non-automatic—are classified, and the programming techniques are explained as a function of machine hardware and other system features. The implementation of a semiautomatic overlay facility in a multiprogrammed system on the CDC 6600 is described in detail, with special reference to real time applications.
