Yabasic (Yet Another BASIC) is a free, open-source BASIC interpreter for Microsoft Windows and Unix platforms. [2] Yabasic was originally developed by Marc-Oliver Ihm, who released the last stable version 2.77.3 in 2016. From version 2.77.1, the project has adopted the MIT License as well as the source code being moved to GitHub to encourage others to participate in its development. [3]

Features

Other versions

Yab

A version optimized for BeOS, ZETA and Haiku. [4]

Flyab

A port of Yabasic to the Fltk toolkit called "Flyab" was under development. It would have been source-compatible with programs written in yab, a variant of Yabasic that enables graphical programs to be written using the BeOS API. After BeOS and its successor ZETA finally were gone, the team members around yab for BeOS decided to move to Linux and therefore chose FLTK to implement the UI parts. Ports for Microsoft Windows, Mac OS X, and Linux would have been possible. Flyab added the ability to Yabasic to create native graphical user interfaces on all supported platforms. Main difficulty was to fully implement the layout commands to FLTK, as used from the BeOS version. [ citation needed ] As of November 2008, the project appears to be halted.

PlayStation 2

Sony also packaged a version of Yabasic for the PlayStation 2 on the demo disc [5] shipped with PS2 consoles in PAL territories so it could be considered a home computer, not just a games machine, thus bypassing European import taxes. [6]

Yabasic 3.0 (Unofficial)

As a continuation of the project prior to new changes by the original author, version 3 was being developed by a team centered on Pedro Sá and Thomas Larsen, but development has halted and the project now appears to be abandoned.[ citation needed ]

Microsoft Windows is a product line of proprietary graphical operating systems developed and marketed by Microsoft. It is grouped into families and sub-families that cater to particular sectors of the computing industry -- Windows (unqualified) for a consumer or corporate workstation, Windows Server for a server and Windows IoT for an embedded system. Defunct families include Windows 9x, Windows Mobile, Windows Phone, and Windows Embedded Compact.

<span class="mw-page-title-main">OpenStep</span> Defunct object-oriented application programming interface specification

OpenStep is an object-oriented application programming interface (API) specification developed by NeXT. It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems. It has influenced the development of other GUI frameworks, such as Cocoa for macOS and GNUstep.

cmd.exe Command prompt program

Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, eComStation, ArcaOS, Microsoft Windows, and ReactOS operating systems. On Windows CE .NET 4.2, Windows CE 5.0 and Windows Embedded CE 6.0 it is referred to as the Command Processor Shell. Its implementations differ between operating systems, but the behavior and basic set of commands are consistent. cmd.exe is the counterpart of COMMAND.COM in DOS and Windows 9x systems, and analogous to the Unix shells used on Unix-like systems. The initial version of cmd.exe for Windows NT was developed by Therese Stowell. Windows CE 2.11 was the first embedded Windows release to support a console and a Windows CE version of cmd.exe. The ReactOS implementation of cmd.exe is derived from FreeCOM, the FreeDOS command line interpreter.

Core Foundation is a C application programming interface (API) written by Apple Inc. for its operating systems, and is a mix of low-level routines and wrapper functions. Most Core Foundation routines follow a certain naming convention that deal with opaque objects, for example CFDictionaryRef for functions whose names begin with CFDictionary, and these objects are often reference counted (manually) through CFRetain and CFRelease. Internally, Core Foundation forms the base of the types in the Objective-C standard library and the Carbon API.

fpGUI, the Free Pascal GUI toolkit, is a cross-platform graphical user interface toolkit developed by Graeme Geldenhuys. fpGUI is open source and free software, licensed under a Modified LGPL license. The toolkit has been implemented using the Free Pascal compiler, meaning it is written in the Object Pascal language.

Vehicle registration plates in Luxembourg bear a maximum of six characters. The standard series in use today uses a format of two letters followed by four digits. Before adoption of the current scheme, marks consisting only of digits and two digits and three numbers letters, were issued. The digit-only plates may only now be issued as a custom plate.
