  • 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.

The Atari 5200 SuperSystem , or simply the Atari 5200 , is a video game console that was introduced in 1982 by Atari as a replacement for the famous Atari 2600. The 5200 was created to compete with the Mattel Intellivision, but wound up more directly competing with the ColecoVision shortly after its release. A number of design flaws had a serious impact on usability, and the system is generally considered a failure. The 5200 was heavily based on Atari's existing 400/800 computers and the internal hardware was almost identical. However, a number of issues (aside from the lack of a keyboard) meant that software was not directly compatible between the two systems.

The Atari 5200 SuperSystem, commonly known as the Atari 5200, is a home video game console that was introduced in 1982 by Atari Inc. as a higher-end complementary console for the popular Atari 2600.

The 5200 was based on Atari Inc.'s existing 400/800 computers and the internal hardware was almost identical, although software was not directly compatible between the two systems. The 5200's controllers have an analog joystick and a numeric keypad along with start, pause and reset buttons.

    Best Electronics Specializing in Replacement Parts and Accessories for all Consumer Based Atari Game Systems and Atari Computers for the Index page / Site listing One of the more common Atari Questions / E-Mails we get, do you really have that Atari part or Atari item in stock. I have checked the world wide Internet and you are the only one that lists it? I noticed that your that your Atari web page(s) have not been updated (bottom of each Best Web page has a last updated date) for weeks, months or years? When we cleared out the local Atari Sunnyvale Warehouses here over a 10 to 15 year period, we hauled in thousands and thousands of Pallets of Atari Goods. Some Atari items we have a lifetime supply of (hence why the Best Atari web page for that product never gets updated) and other Atari items have sold out fast to the world wide Atari users and collectors.

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.

Thank you so much, we really appreciate your help. You are now in the hall of fame. Thank you Mike Silva!!! Further credit goes to Brian Lee, the product manager, who was very involved in guiding the look- and-feel and the overall functionality of the program. Thanky you so much Mr. Lee, we really appreciate your help, then and now. :-) Because the source code listing as well as the disk files are lost, it would be cool, if someone out there is in the possession of that, if you can share it with the community. Many thanks in advance. :-) Officially, 2 version were sold, one from 1983 and the other from 1985. Of course, there are others out there in the web, mostly patched and cracked ones.
