    The MSX Red Book (revised version 1997/08/06) Notes from the editor: - The book was scanned and converted (via O.C.R.) by one person and edited by another (using an IBM PC compatible), independently. - All pages have a fix size of 64 lines. The width was not justified to make future modifications easier, though no line is longer than 80 columns. - This book only covers standard MSX. The BIOS entry points from 0000H to 01B5H should be used instead of the called entries described in the book, because other machines (MSX2, MSX2+, MSX turbo R and customized ones) have different positions for the routines. The use of internal BIOS routine addresses are responsible for many programs only running in MSX. - Some errors present in the original book were fixed, though it was tried to keep it as unaltered as possible. All page numbers match the originals, except undetected errors already present in the original. - Most figures were modificated due to the text-only nature of this file. The character set used during edition was the International IBM PC's one. The following special characters were used and should be changed to the corresponding ones of other character sets: Frame ÚÄÂÄ¿ Pound: œ characters: ³ ³ ³ Micro: æ ÃÄÅÄ´ ³ ³ ³ ÀÄÁÄÙ ------------------------------------------------------------------------------- CONTENTS Introduction .............................. 1 1.

  • Freebasic-Einsteigerhandbuch
    FreeBASIC-Einsteigerhandbuch Grundlagen der Programmierung in FreeBASIC von S. Markthaler Stand: 11. Mai 2015 Einleitung 1. Über das Buch Dieses Buch ist für Programmieranfänger gedacht, die sich mit der Sprache FreeBASIC beschäftigen wollen. Es setzt keine Vorkenntnisse über die Computerprogrammierung voraus. Sie sollten jedoch wissen, wie man einen Computer bedient, Programme installiert und startet, Dateien speichert usw. Wenn Sie bereits mit Q(uick)BASIC gearbeitet haben, finden Sie in Kapitel 1.3 eine Zusammenstellung der Unterschiede zwischen beiden Sprachen. Sie erfahren dort auch, wie Sie Q(uick)BASIC-Programme für FreeBASIC lauffähig machen können. Wenn Sie noch über keine Programmiererfahrung verfügen, empfiehlt es sich, die Kapitel des Buches in der vorgegebenen Reihenfolge durchzuarbeiten. Wenn Ihnen einige Konzepte bereits bekannt sind, können Sie auch direkt zu den Kapiteln springen, die Sie interessieren. 2. In diesem Buch verwendete Konventionen In diesem Buch tauchen verschiedene Elemente wie Variablen, Schlüsselwörter und besondere Textabschnitte auf. Damit Sie sich beim Lesen schnell zurechtfinden, werden diese Elemente kurz vorgestellt. Befehle und Variablen, die im laufenden Text auftauchen, werden in nichtproportionaler Schrift dargestellt. Schlüsselwörter wie PRINT werden in Fettdruck geschrieben, während für andere Elemente wie variablenname die normale Schriftstärke eingesetzt wird. Quelltexte werden vollständig in nichtproportionaler Schrift gesetzt und mit einem Begrenzungsrahmen dargestellt. Auch hier werden Schlüsselwörter fett gedruckt. Der Dateiname des Programms wird oberhalb des Quelltextes angezeigt. Quelltext 1.1: Hallo Welt ’ Kommentar: Ein gewoehnliches Hallo-Welt-Programm CLS PRINT "Hallo FreeBASIC-Welt!" SLEEP 5 END ii Einleitung Es empfiehlt sich, die Programme abzutippen und zu testen. Die meisten Programme sind sehr kurz und können schnell abgetippt werden – auf der anderen Seite werden Sie Codebeispiele, die Sie selbst getippt haben, leichter behalten.

  • BASIC Programming with Unix Introduction
    LinuxFocus article number 277 http://linuxfocus.org BASIC programming with Unix by John Perr <johnperr(at)Linuxfocus.org> Abstract: About the author: Developing with Linux or another Unix system in BASIC ? Why not ? Linux user since 1994, he is Various free solutions allows us to use the BASIC language to develop one of the French editors of interpreted or compiled applications. LinuxFocus. _________________ _________________ _________________ Translated to English by: Georges Tarbouriech <gt(at)Linuxfocus.org> Introduction Even if it appeared later than other languages on the computing scene, BASIC quickly became widespread on many non Unix systems as a replacement for the scripting languages natively found on Unix. This is probably the main reason why this language is rarely used by Unix people. Unix had a more powerful scripting language from the first day on. Like other scripting languages, BASIC is mostly an interpreted one and uses a rather simple syntax, without data types, apart from a distinction between strings and numbers. Historically, the name of the language comes from its simplicity and from the fact it allows to easily teach programming to students. Unfortunately, the lack of standardization lead to many different versions mostly incompatible with each other. We can even say there are as many versions as interpreters what makes BASIC hardly portable. Despite these drawbacks and many others that the "true programmers" will remind us, BASIC stays an option to be taken into account to quickly develop small programs. This has been especially true for many years because of the Integrated Development Environment found in Windows versions allowing graphical interface design in a few mouse clicks.

  • Assignment #6—Basic Due Date: Friday, March 13 Note: Assignment #6 Will Not Be Accepted After 5:00P.M
    Eric Roberts Handout #44 CS 106B February 27, 2015 Assignment #6—Basic Due date: Friday, March 13 Note: Assignment #6 will not be accepted after 5:00P.M. on Monday, March 16 – 2 – In 1975, Bill Gates and Paul Allen started the company that would become Microsoft by writing a BASIC interpreter for the first microcomputer, the Altair 8800 developed by the MITS Corporation of Albuquerque, New Mexico. By making it possible for users to write programs for a microcomputer without having to code in machine language, the Altair and its implementation of BASIC helped to start the personal computer revolution. In this assignment, your mission is to build a minimal BASIC interpreter, starting with the code for the integer expression evaluator presented in Chapter 19. This assignment is designed to accomplish the following objectives: • To increase your familiarity with expression trees and class inheritance. • To give you a better sense of how programming languages work. Learning how an interpreter operates—particularly one that you build yourself—provides useful insights into the programming process. • To offer you the chance to adapt an existing program into one that solves a different but related task. The majority of programming that people do in the industry consists of modifying existing systems rather than creating them from scratch. What is BASIC? The programming language BASIC—the name is an acronym for Beginner’s All-purpose Symbolic Instruction Code—was developed in the mid-1960s at Dartmouth College by John Kemeny and Thomas Kurtz. It was one of the first languages designed to be easy to use and learn.

One big dierence from other BASIC interpreters in 1980s era 8-bit computers is the lack of line numbers, as well as an integrated full-screen editor. This is similar to newer programming environments, giving 1 FastBasic 4.3 - Fast BASIC interpreter for the Atari 8-bit computers the programmer a higher degree of flexibility. Another big dierence is that default variables and operations are done using integer numbers; this is one of the reasons that the programs run so fast relative to its peers from the 1980s. The other reason is that the program is parsed on run, generating optimized code for very fast execution.
