In a few millionths of a second, common electrical surges and spikes can enter your data processing equipment and cause memory loss, false logic and misregistration. Surges very often do permanent damage to microcircuitry. FLEXIDIKT Surge Suppressors catch surges and spikes before they have a chance to enter your equipment In billionths of a second (Nanoseconds),FLEXIDIKT Surge Suppressors dissipate surges and spikes from any side of the line (most protect only one side). The multi-outlet unit is ideally suited to the computerized work­ station. It gives you the advantage of circuit breaker protection with plenty of outlets for data processor and peripheral equipment No computer should be without the protection of a FLEXIDUCT Surge Suppressor...especially yours!

  • BASIC Programming with Unix Introduction

    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.

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.

    Microtype The microtype package An interface to the micro-typographic extensions of pdfTEX R Schlicht [email protected] v1.9 — 2005/10/28 Abstract The microtype package provides an interface to the micro-typographic extensions of pdfTEX: most prominently, character protrusion and font expansion, furthermore the possibility to disable all ligatures of a font.1 It allows to apply these features to customizable sets of fonts, and to configure all micro-typographic aspects of the fonts in a straight-forward and flexible way. Settings for various fonts are provided.2 Note that font expansion and character protrusion will only work with pdfTEX, at least version 0.14f. Automatic font expansion requires version 1.20 or newer. Disabling ligatures require pdfTEX 1.30. The package will by default enable the features that can safely be assumed to work. 1 A preview of the next version with support for even more micro-typographical extensions is also included in this package. Footnote 12 on page 17 contains the details. 2 Currently, this package provides settings for Computer Modern Roman, Palatino, Times, Adobe Garamond and Minion, Bitstream Charter, and the AMS math fonts, as well as some generic settings for unknown fonts.

I have re-disassembled the ROMs listed in this book, and added all the comments from the Original Extended Basic Unravelled Book. Some changes were made to make the book a little easier to read. 1. The comments have been cleaned up some. In cases where a comments continued onto the next line, a * is placed in the Labels column, as well as a * at the beginning of each line of the comment. In cases where the previous comment used this format, a = was used. This was done in the original, but not all comments stuck to this format. 2. I have renumbered all the line numbers. Each Appendix (with code) starts at Line 0001. 3. Some spell checking, and context checking was done to verify accuracy. 4. I used the Letter Gothic MT Bold Font.
