Microsoft Qbasic
 

QBasic was intended as a replacement for GW-BASIC. It was based on the earlier QuickBASIC 4.5 compiler but without QuickBASIC's compiler and linker elements. Version 1.0 was shipped together with MS-DOS 5.0 and higher, as well as Windows 95, Windows NT 3.x, and Windows NT 4.0. IBM recompiled QBasic and included it in PC-DOS 5.x, as well as OS/2 2.0 onwards.[7] eComStation, descended from OS/2 code, includes QBasic 1.0. QBasic 1.1 is included with MS-DOS 6.x, and, without EDIT, in Windows 95, Windows 98 and Windows Me. Starting with Windows 2000, Microsoft no longer includes QBasic with their operating systems.[8] (However, some localized versions of Windows 2000 and Windows XP still have it,and it can be given out as freeware.)

QBasic (as well as the built-in MS-DOS Editor) is backward compatible with DOS releases prior to 5.0 (down to at least DOS 3.20). However, if used on any 8088/8086 computers, or on some 80286 computers, the QBasic program may run very slowly, or perhaps not at all, due to its memory size. Until MS-DOS 7, MS-DOS Editor required QBasic. The "edit.com" program simply starts QBasic in editor mode only, and this mode can also be entered by running QBASIC.EXE with the /EDIT switch (i.e., command line "QBASIC /EDIT").

Here are some sample games in their source code.

 

***TIC TAC TOE***

The game you all know, written in Qbasic by Daniel Rowe.

Featuring an "active" game board and freedom to change

the controls to suit your needs.

 

***GUESS MY NUMBER***

A very simple guessing game in which you try to guess

what number, from 1-10, the computer has picked in 5

guesses.

 

 

Miscrosoft Visual Basic

 

Visual Basic (VB) is the third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model. VB is also considered a relatively easy to learn and use programming language, because of its graphical development features and BASIC heritage.[1]

Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects. Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but perform differently.[2]

A programmer can put together an application using the components provided with Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations.

The final release was version 6 in 1998. Microsoft's extended support ended in March 2008 and the designated successor was Visual Basic .NET (now known simply as Visual Basic).

 

Unreal's Level Editor

 

UnrealEd (UEd for short) is the level editor used to create levels for Unreal. It was also used for other games based on the Unreal engine, such as Deus Ex and Lineage II, although it has changed along with the engine for later games. One of the first companies to do this with first person shooters,[1] all Unreal games on the PC had the level editor included for free, and some third party Unreal engine games did the same with an edited and specialized version. This extended the longevity of the games. Amateur level designers could now create their own levels for the game, providing a near endless amount of additional content for the game. In addition, the built-in scripting language called UnrealScript allowed for editors to customize game content.

UnrealEd has a customizable user interface, but the most common is the quad viewports with the top view in the top left, then, moving clockwise, the front view, the side view, and the perspective view. It has a row of buttons along the top pertaining to various options such as save, open, and rebuild, and a series of buttons to the left of the viewports which access editing functions.

 

Sun Microsystem's Java

 

Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is considered by many as one of the most influential programming languages of the 20th century, and widely used from application software to web application.[9][10]

The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of their Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.
