Additional functionality not normally seen in BASIC languages are function callbacks and primitive object-orientation. The language is called semi-object-oriented by its author because there are only two levels of the class hierarchy: built-in classes, and user-defined classes derived from those; the latter cannot be extended further. The ability to call external shared libraries is available, thus giving full access to the underlying operating system's application program interface. Other capabilities include built-in interfaces to DirectX and MySQL.
RapidQ features a bytecode compiler that produces standalone executables by binding the generated bytecode with the interpreter. No external run time libraries are needed; the bytecode interpreter is self-contained. The file sizes of executable files created by RapidQ are about 150 kilobytes or larger for console applications.
RapidQ's author, William Yu, sold the source code to REAL Software, the makers of REALbasic, in 2000. The freely distributed program has been improved and many additional components have been created by an active user group.
An integrated development environment (IDE) is a software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, and a debugger. Some IDEs, such as IntelliJ IDEA, Eclipse and Lazarus contain the necessary compiler, interpreter or both; others, such as SharpDevelop and NetBeans, do not.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities that are typically not available in traditional compiled languages.
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform.
Liberty BASIC (LB) is a commercial computer programming language and integrated development environment (IDE). It has an interpreter, developed in Smalltalk, which recognizes its own dialect of the BASIC programming language. It runs on 16- and 32-bit Windows and OS/2.
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution:
Parse the source code and perform its behavior directly;
Translate source code into some efficient intermediate representation or object code and immediately execute that;
Explicitly execute stored precompiled bytecode made by a compiler and matched with the interpreter Virtual Machine.
PureBasic is a commercially distributed procedural computer programming language and integrated development environment based on BASIC and developed by Fantaisie Software for Windows, Linux, and macOS. An Amiga version is available, although it has been discontinued and some parts of it are released as open-source. The first public release of PureBasic for Windows was on 17 December 2000. It has been continually updated ever since.
ScriptBasic is a scripting language variant of BASIC. The source of the interpreter is available as a C program under the LGPL license.
Genera is a commercial operating system and integrated development environment for Lisp machines created by Symbolics. It is essentially a fork of an earlier operating system originating on the Massachusetts Institute of Technology (MIT) AI Lab's Lisp machines which Symbolics had used in common with Lisp Machines, Inc. (LMI), and Texas Instruments (TI). Genera was also sold by Symbolics as Open Genera, which runs Genera on computers based on a Digital Equipment Corporation (DEC) Alpha processor using Tru64 UNIX. In 2021 a new version was released as Portable Genera which runs on Tru64 UNIX on Alpha, Linux on x86-64 and Arm64 Linux, and macOS on x86-64 and Arm64. It is released and licensed as proprietary software.
PowerBASIC, formerly Turbo Basic, is the brand of several commercial compilers by PowerBASIC Inc. that compile a dialect of the BASIC programming language. There are both MS-DOS and Windows versions, and two kinds of the latter: Console and Windows. The MS-DOS version has a syntax similar to that of QBasic and QuickBASIC. The Windows versions use a BASIC syntax expanded to include many Windows functions, and the statements can be combined with calls to the Windows API.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
Bytecode is a form of instruction set designed for efficient execution by a software interpreter. Unlike human-readable source code, bytecodes are compact numeric codes, constants, and references that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of program objects.
Object Pascal is an extension to the programming language Pascal that provides object-oriented programming (OOP) features such as classes and methods.
Factor is a stack-oriented programming language created by Slava Pestov. Factor is dynamically typed and has automatic memory management, as well as powerful metaprogramming features. The language has a single implementation featuring a self-hosted optimizing compiler and an interactive development environment. The Factor distribution includes a large standard library.
The Parallax P8X32A Propeller is a multi-core processor parallel computer architecture microcontroller chip with eight 32-bit reduced instruction set computer (RISC) central processing unit (CPU) cores. Introduced in 2006, it is designed and sold by Parallax, Inc.
A scripting language or script language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. Scripting languages are usually interpreted at runtime rather than compiled.
Basic4ppc is a programming language originally for Pocket PC handheld computers running Windows Mobile operating system, by Anywhere Software. Since 2014, B4x was renamed, and currently, 2023, supports multiple devices and their OS, including desktop and mobile solutions with development adaptions for these environments. The language is based on a BASIC-like syntax, taking advantage of Microsoft's .NET technology, to allow additional libraries, graphical user interface design of windows forms, rapid application development (RAD), and .NET framework compatible compilation. The language implements a unique way of adding objects to a program without being object-oriented. Its advantages are simplicity, development pace and the integration with .NET framework. A special version of the integrated development environment (IDE) allows developing straight onto the Windows Mobile device or. With the demise of Windows Mobile operating system and the devices running it Basic4PPC came to the end of its life in about 2012. For owners of Basic4PPC it remains a useful Windows-desktop BASIC compiler as it runs code directly in the Windows environment and it can compile a project to a Windows 'exe' file for use as a Windows program.
A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command-lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as a user-friendly alternative to punched cards.
