About the book: 2005 / The book discusses the basic theoretical foundations necessary for building compilers, the main technological techniques and methods for their implementation. It provides various options for tasks for completing a laboratory workshop in the “System Software” course, as well as examples of completing these tasks. Each example discusses in detail all the features of its implementation, both at the stage of preparing the necessary mathematical base, and at the stage of software implementation. In laboratory work, the author draws attention to the main difficulties associated with its implementation, as well as possible typical errors and shortcomings, and gives recommendations on the possibilities of software implementation that differ from the code given in the examples. The book is aimed at students studying at technical universities in specialties related to computer technology. But it will also be useful to everyone whose activities in one way or another relate to software development.
