The Design of a Pascal Compiler Mohamed Sharaf, Devaun Mcfarland, Aspen Olmsted Part I
The Design of A Pascal Compiler Mohamed Sharaf, Devaun McFarland, Aspen Olmsted Part I Mohamed Sharaf Introduction The Compiler is for the programming language PASCAL. The design decisions Concern the layout of program and data, syntax analyzer. The compiler is written in its own language. The compiler is intended for the CDC 6000 computer family. CDC 6000 is a family of mainframe computer manufactured by Control Data Corporation in the 1960s. It consisted of CDC 6400, CDC 6500, CDC 6600 and CDC 6700 computers, which all were extremely rapid and efficient for their time. It had a distributed architecture and was a reduced instruction set (RISC) machine many years before such a term was invented. Pascal Language Imperative Computer Programming Language, developed in 1971 by Niklaus Wirth. The primary unit in Pascal is the procedure. Each procedure is represented by a data segment and the program/code segment. The two segments are disjoint. Compiling Programs: Basic View Machine Pascal languag program Pascal e compile program filename . inpu r gp output a.out p t c Representation of Data Compute all the addresses at compile time to optimize certain index calculation. Entire variables always are assigned at least one full PSU “Physical Storage Unit” i.e CDC6000 has ‘wordlength’ of 60 bits. Scalar types Array types the first term is computed by the compiler w=a+(i-l)*s Record types: reside only within one PSU if it is represented as packed. If it is not packed its size will be the size of the largest possible variant. Data types … Powerset types The set operations of PASCAL are realized by the conventional bit-parallel logical instructions ‘and ‘ for intersection, ‘or’ for union File types The data transfer between the main store buffer and the secondary store is performed by a Peripheral Processor (PP). -

Language Interoperability in Control Network Programming
International Journal of Science and Engineering Investigations vol. 7, issue 78, July 2018 ISSN: 2251-8843 Language Interoperability in Control Network Programming Kostadin Kratchanov1, Efe Ergün2 1,2Yaşar University, Izmir, Turkey ([email protected], [email protected]) Abstract - Control Network Programming (CNP) is a There is a number of reasons why language interoperability programming paradigm which is being described with the is highly desirable. For example, if a programmer has to maxim “Primitives + Control Network = Control Network implement a specific feature that has been already implemented program”. It is a type of graphic programming. The Control in another language the corresponding program component can Network is a recursive system of graphs; it can be a purely simply be reused. Some languages are especially fit and descriptive specification of the problem being solved. Clearly, effective in implementing specific features and often have ‘drawing’ the control network does not include any emerged to target particular problem domains. Rich third-party programming. The Primitives are elementary, easily packages for certain languages are available. Also, every understandable and clearly specified actions. Ultimately, they programmer usually has a preferred language in which their have to be programmed. Historically, they are usually coded in expertise and efficiency is better. There are hundreds of Free Pascal. The actual code of the primitives has never been programming languages used and constantly being developed considered important. The essence of an “algorithm” is thus making language interoperability a necessity. represented by its control network. CNP was always meant to Programmers with experience and preferences in different be an easy and fast approach for software application programming languages can easier team up for solving development that actually involves very little real complex tasks. -

Competition Environment
Competition Environment Contents 1 General 2 2 Hardware 2 3 Linux 2 4 Windows 4 1 CEOI 2003, Germany Competition environment 1 General Please first check the general information about the competition programming environment from the Competition Rules. The main environment for the contest is Linux. Linux is available as a programming environment (specifications below) and also the servers and evaluation (grading) runs on Linux. However, we provide the contestants with dual-boot computers where you can program either in Linux or in Windows environment. The evaluation is based on source-code submission and the evaluation system compiles the sub- mitted source code. As a consequence, also the programs written in the Windows environment are re-compiled for evaluation in Linux (using the same compiler). This is something that all contes- tants using Windows must be aware of. For example, uninitialized variables may cause undefined behavior when executing for the evaluation. We favor fairly standard operating system installations, but we may modify the installations for hardware support and security fixes. The compilers used in the competition are GCC for C and C++ programs and Freepascal for Pascal programs. Generally, the installations are designed for the following main alternatives: 1. Pascal as the programming language, Freepascal compiler, Freepascal IDE or RHIDE IDE. 2. C/C++ as the programming language, GCC compiler, RHIDE IDE. 3. Editors (emacs, vim, ...), command-line compilation/debugging, a graphical front end ddd for debugging. Option 3 is targeted primarily for Linux, although it is possible to use Windows Edit and command- line compilation. 2 Hardware The competition computers have Pentium III/650 MHz or better processor, 128 MB or more RAM, a standard UK keyboard, a mouse, and a color screen. -

Chesnokova, T. V. Kucher M.: ALTLinux; Publishing house DMK-Press, 2010. 440 p.: illustrated.(ALT Linux library). ISBN 978-5-94074-611-9 Free Pascal is a free implementation of the Pascal programming language that is compatible with Borland Pascal and Object Pascal / Delphi, but with additional features. The Free Pascal compiler is a free cross-platform product implemented on Linux and Windows, and other operating systems. This book is a textbook on algorithms and programming, using Free Pascal. The reader will also be introduced to the principles of creating graphical user interface applications with Lazarus. Each topic is accompanied by 25 exercise problems, which will make this textbook useful not only for those studying programming independently, but also for teachers in the education system. The book’s website is: http://books.altlinux.ru/freepascal/ This textbook is intended for teachers and students of junior colleges and universities, and the wider audience of readers who may be interested in programming.
