  • [Catalog Epub PDF] Scriptbasic Manual
    Scriptbasic Manual Download Scriptbasic Manual These numbers, strings etc are known as data types.In fact, VBScript has only one data type called Variant. A variant is a special kind of data type which can hold different kinds of information. The value of 0 disables the history feature. For more information, read the user manuals for the GNU readline, history and BSD libedit libraries. One can not enable both readline and libedit at the same time. GNU bc and Other Implementations There are many tutorials available for AutoIt. This page is an overview of a few known tutorials. More tutorials can possibly be found and will be added to this page in time. I did all I could to help you, short of actually looking at the internals of ScriptBasic and running it. I pointed at what was my best guess at the source of the issue (treating v7_val_t as a long , which is incorrect and indeed breaks 32-bit archs) and asked for stack traces which you didn't provide. SOPEN now works as described in the manual. I was able to read and write data to my usb to i2c interface which I was using to display time (hours and minutes) on a adafruit 7 segment LED and read a DS1621 thermometer and display it on a SAA1064 4 by 7 segment LED a very old Elektor magazine project.

  • How to Write ZX Spectrum Games
    How to Write ZX Spectrum Games Version 1.0 Jonathan Cauldwell Document History Version 0.1 - February 2006 Version 0.2 - January 2007 Version 0.3 - December 2008 Version 0.4 - July 2009 Version 0.5 - October 2010 Version 0.6 - April 2014 Version 1.0 - June 2015 Copyright All rights reserved. No part of this document may be reproduced in any form without prior written permission from the author. Introduction So you've read the Z80 documentation, you know how the instructions affect the registers and now you want to put this knowledge to use. Judging by the number of emails I have received asking how to read the keyboard, calculate screen addresses or emit white noise from the beeper it has become clear that there really isn't much in the way of resources for the new Spectrum programmer. This document, I hope, will grow to fill this void in due course. In its present state it is clearly years from completion, but in publishing the few basic chapters that exist to date I hope it will be of help to other programmers. The ZX Spectrum was launched in April 1982, and by today's standards is a primitive machine. In the United Kingdom and a few other countries it was the most popular games machine of the 1980s, and through the joys of emulation many people are enjoying a nostalgic trip back in time with the games of their childhoods. Others are only now discovering the machine for the first time, and some are even taking up the challenge of writing games for this simple little computer.

  • The Spectrum Memory Map 95 Kramer, Steve Appendix C the Spectrum Screen Map 96 the Spectrum Operating System
    THE SPECTRUM OPERATING SYSTEM This book will be a valuable asset to all Spectrum owners. There is a wealth of material enabling you to employ versatile techniques which are normally the domain of the professional. The author shows how short machine code routines can be written and used very easily. A number of programs which are ready to type in are also included. For the machine code programmer, this book will be a constant source of reference. Instead of 're-inventing the wheel' for each new program, the author shows you how to make full use of ROM routines and the existing facilities. Both the Spectrum and the microdrive interface are covered, and there is a detailed description of extending the operating system for microdrive users. The Author Steve Kramer has been working with computers for twelve years. He acts as an independent software consultant to a number of software houses in the field of business applications. He is also the author of several games and home-use programs written for popular micros. ^ —^^,' ^._ ---•e^^ nnnnnn GB f NET +095.95 111111 ISBN 0 - 7447 - 9019 - 1 00595 The Spectrum Operating System The Spectrum Operating System Steve Kramer /W/ MICRO PRESS Contents First Published 1984 by Chapter 1 Getting Started 1 Micro Press Chapter 2 Useful Call Addresses and How to Use Them: the Castle House, 27 London Road Tunbridge Wells, Kent 16K ROM 3 Chapter 3 The 8K Interface ROM 25 © Steve Kramer 1984 Chapter 4 The System Variables 42 All rights reserved.

  • Discovering Eastern European Pcs by Hacking Them. Today
    Discovering Eastern European PCs by hacking them. Today Stefano Bodrato, Fabrizio Caruso, Giovanni A. Cignoni Progetto HMR, Pisa, Italy {stefano.bodrato, fabrizio.caruso, giovanni.cignoni}@progettohmr.it Abstract. Computer science would not be the same without personal comput- ers. In the West the so called PC revolution started in the late ’70s and has its roots in hobbyists and do-it-yourself clubs. In the following years the diffusion of home and personal computers has made the discipline closer to many people. A bit later, to a lesser extent, yet in a similar way, the revolution took place also in East European countries. Today, the scenario of personal computing has completely changed, however the computers of the ’80s are still objects of fas- cination for a number of retrocomputing fans who enjoy using, programming and hacking the old “8-bits”. The paper highlights the continuity between yesterday’s hobbyists and today’s retrocomputing enthusiasts, particularly focusing on East European PCs. Be- sides the preservation of old hardware and software, the community is engaged in the development of emulators and cross compilers. Such tools can be used for historical investigation, for example to trace the origins of the BASIC inter- preters loaded in the ROMs of East European PCs. Keywords: 8-bit computers, emulators, software development tools, retrocom- puting communities, hacking. 1 Introduction The diffusion of home and personal computers has made information technology and computer science closer to many people. Actually, it changed the computer industry orienting it towards the consumer market. Today, personal computing is perceived as a set of devices – from smartphones to videogame consoles – made just to be used.

  • Anexo:Lista De Linguagens De Programação
    Anexo:Lista de linguagens de programação Origem: Wikipédia, a enciclopédia livre. É praticamente incontável o número de linguagens de programação. Uma mesma linguagem, inclusive, pode aparecer em várias versões, como Fortran, Lisp e BASIC, todas com detalhes que variam do insignificante ao que poderia ser chamado de dialeto e outros que configuram uma linguagem claramente diferente, como Fortran 66 e Fortran 99. Ao longo dos anos, certamente milhares de linguagens foram propostas, descritas, implementadas e usadas por diferentes pessoas. Entre essas linguagens, algumas obtiveram sucesso pleno e são reconhecidas, como BASIC, C, C++, COBOL, Fortran, Java e Pascal. Outras tiveram grande influência acadêmica, mas são conhecidas apenas por alguns ou por sua importância histórica, como Simula 67, BCPL, CLU etc. Existem linguagens pouco reconhecidas, mas reputadas em seus nichos de mercado, como Forth, Jovial etc. Outras linguagens passaram, deixaram sua marca em alguns programadores, mas foram abandonadas com a passagem do momento tecnológico que as tornava interessantes, como Clipper e Snobol 4. Finalmente, algumas linguagens e dialetos nunca conseguiram reconhecimento, ou foram apenas propostas teóricas ou usadas em poucas localidades, sendo provavelmente desconhecidas da maior parte dos interessados na área, como Smalltalk 72 (um predecessor de Smalltalk 80). A lista seguinte é uma tentativa de oferecer ao leitor uma visão ampla de várias linguagens disponíveis no passado e no presente. No entanto, ela não configura uma tentativa de listar
