  • Xbase++ Language Concepts for Newbies Geek Gatherings Roger Donnay
    Xbase++ Language Concepts for Newbies Geek Gatherings Roger Donnay Introduction Xbase++ has extended the capabilities of the language beyond what is available in FoxPro and Clipper. For FoxPro developers and Clipper developers who are new to Xbase++, there are new variable types and language concepts that can enhance the programmer's ability to create more powerful and more supportable applications. The flexibility of the Xbase++ language is what makes it possible to create libraries of functions that can be used dynamically across multiple applications. The preprocessor, code blocks, ragged arrays and objects combine to give the programmer the ability to create their own language of commands and functions and all the advantages of a 4th generation language. This session will also show how these language concepts can be employed to create 3rd party add-on products to Xbase++ that will integrate seamlessly into Xbase++ applications. The Xbase++ language in incredibly robust and it could take years to understand most of its capabilities, however when migrating Clipper and FoxPro applications, it is not necessary to know all of this. I have aided many Clipper and FoxPro developers with the migration process over the years and I have found that only a basic introduction to the following concepts are necessary to get off to a great start: * The Xbase++ Project. Creation of EXEs and DLLs. * The compiler, linker and project builder . * Console mode for quick migration of Clipper and Fox 2.6 apps. * INIT and EXIT procedures, DBESYS, APPSYS and MAIN. * The DBE (Database engine) * LOCALS, STATICS, PRIVATE and PUBLIC variables. * STATIC functions.

  • The Origins of Word Processing and Office Automation
    Remembering the Office of the Future: The Origins of Word Processing and Office Automation Thomas Haigh University of Wisconsin Word processing entered the American office in 1970 as an idea about reorganizing typists, but its meaning soon shifted to describe computerized text editing. The designers of word processing systems combined existing technologies to exploit the falling costs of interactive computing, creating a new business quite separate from the emerging world of the personal computer. Most people first experienced word processing using a word processor, we think of a software as an application of the personal computer. package, such as Microsoft Word. However, in During the 1980s, word processing rivaled and the early 1970s, when the idea of word process- eventually overtook spreadsheet creation as the ing first gained prominence, it referred to a new most widespread business application for per- way of organizing work: an ideal of centralizing sonal computers.1 By the end of that decade, the typing and transcription in the hands of spe- typewriter had been banished to the corner of cialists equipped with technologies such as auto- most offices, used only to fill out forms and matic typewriters.

  • Unit 6: Computer Software
    Computer Software Unit 6: Computer Software Introduction Collectively computer programs are known as computer software. This unit consisting of four lessons presents different aspects of computer software. Lesson 1 introduces software and its classification, system software which assists the users to develop programs for solving user problems is presented in Lesson 2. Many programs for widely used applications are available commercially. These programs are popularly known as application packages or package programs or simply packages. Advantages of package programs and brief outline of popular packages for word-processing, spreadsheet analysis, database management systems, desktop publication and graphic and applications are discussed in Lesson 3. Tasks for developing computer programs and brief introduction to some common programming languages are presented in Lesson 4. Lesson 1: Introduction and Classification 1.1 Learning Objectives On completion of this lesson you will be able to • understand the concept of software • distinguish between system software and application software • know components of system software and types of application software. 1.2 Software Software of a computer system is intangible rather than physical. It is the term used for any type of program. Software consists of statements, which instruct a computer to perform the required task. Without software a computer is simply a mass of electronic components. For a computer to input, store, make decisions, arithmetically manipulate and Software consists of output data in the correct sequence it must have access to appropriate statements, which instruct programs. Thus, the software includes all the activities associated with a computer to perform the required task. the successful development and operation of the computing system other than the hardware pieces.

  • Reviews Computer Applications Programs
    REVIEWS COMPUTER APPLICATIONS PROGRAMS INTRODUCTION TO SOFTWARE REVIEWS By Glen McAninch, University of Kentucky "You've come a long way baby!!!" Archivists have come a long way from the development of SPINDEX in the early 1970s. Back then, it seemed that archiv- ists needed software written for mainframe computers in order to have the flex- ibility (i. e. variable length fields and user designated tags) and storage capacity necessary to store and retrieve information on archival material. While SPIN- DEX has not been completely superceded for certain applications (i. e., print- ing lists for large institutions with a high volume of data), archivists in the 1980s have found that micro- and minicomputers can provide a relatively low cost alternative which can offer new features such as on-line searching and the generation of statistics. It was in the early 1980s that I first heard of archivists using commercially available software on microcomputers. They were using word processors and file managers like PFS, Data Factory, and DB Master on Apple computers with limited memory. Later, archivists stepped up to IBM PCs and look-alikes with two or three times the internal memory of the Apples. This enabled them to use more sophisticated relational database managers such as dBase II and later SAVVY, which require programming through the use of a command language. Archivists also began mixing powerful computers and mass storage (fixed disk) with simple file managers, some of which are reviewed in this issue of The Mid- western Archivist. Another software package that took advantage of the added power of the IBM PC was MARCON, a'database manager written especially for archivists by AIRS, a software developer group-with an archival background.

    Martin Campbell-Kelly Not Only Microsoft: The Maturing of the Personal Computer Software Industry, 1982-1995 In the thirteen years following the introduction of IBM's first personal computer in 1982, Microsoft rose from being a small concern to become the colossus of the PC software industry. However, Microsoft was not the only software company to profit from the PC-software boom: firms like AutoDesk, Lotus Development, WordPerfect Corp., Ashton-Tate, Novell, Borland, Adobe Systems, Aldus, Symantec, and the Santa Cruz Operation all had their time in the sun. Whereas some of these firms lost their markets to Microsoft or stumbled through strategic errors, others remained hugely successful, and their relative obscurity is largely due to the contemporary obsession with Microsoft and its billionaire founder. he early history of the personal computer is well known. It has fea- Ttured in the press, in numerous popular histories of computing, and in television programs such as Robert X.
