History (major versions)

Version 1.00 of Basic4ppc was released in 2005. It was targeted mainly for handheld devices, letting users program in a unique device IDE. Basic concepts where introduced there, such as the direct naming reference and the syntax.

Version 2.0 added major improvements with user interface, controls and optimization.

8/2006 - Version 3.0 released, improved stability, allowed stand-alone compiling for first time.

12/2006 - Version 4.0 released, introduced ability to use external libraries for first time.

5/2007 - Version 5.0 released, with fully new IDE and support for Smartphones.

12/2007 - Version 6.0 created a breakthrough, introduced optimized compiling, thus allowing far better performance on both device and desktop compiled applications.

10/2008 - Version 6.5 released, introduced modules support.

06/2009 - Version 6.8 released, with automatic support for different screen resolutions and addition of two new collections objects.

04/2010 - Version 6.9 released, added support for typed variables and subs.

Android

In 2010 a version for Android phones/tablets was released, this is a separate environment working along the same lines and the language is "basic" like and can be compiled to Android devices. Basic4Android homepage

Language features

Dual development platform: Basic4ppc allows development straight on the handheld device via a fully compatible Device IDE. Code written on either device or desktop IDEs is identical for both platforms and operating systems. Compilation, however, must target either device or desktop, due to the difference in the operating system

Characteristics

Event (computing)
In computing an event is an action that is usually initiated outside the scope of a program and that is handled by a piece of code inside the program. Typically events are handled synchronous with the program flow, that is, the program has one or more dedicated places where events are handled...

. Like most modern languages, the development environment supplies graphical user interface design tools. Users build applications using the drag and drop, component based UI. This is possible on both Device and Desktop, being unique in this ability.

Regular flow structures, such as if…then and for…next are supported, as in many other Basic versions.

Reserved words: Basic4ppc includes a vast number of reserved words. This is because of variable declaration scope.

Variables can be local (accessible throughout a subroutine), global (accessible throughout a module) or public (accessible throughout a program). All variables are typeless. This means you can write the following code:

Sub App_Start
numA = "Five "
numB = "5"
numC = 6

SUM1 = numA & numB 'remark: = "Five 5"
SUM2 = numB + numC 'remark: = 11
End Sub

There is no need to declare variables explicitly.

Subroutines (called "Sub") are the most basic unit of code. All code must be written inside subroutine
Subroutine
In computer science, a subroutine is a portion of code within a larger program that performs a specific task and is relatively independent of the remaining code....

s. Subroutines can return a value.

Direct Naming Reference: All internal controls can be accessed directly and passed as parameters to subroutines by specifying their name expressed as a string
String (computer science)
In formal languages, which are used in mathematical logic and theoretical computer science, a string is a finite sequence of symbols that are chosen from a set or alphabet....

. This lets the programmer the ability to pass controls as parameters without knowing in advance the control that is to be passed, and without having to deal with either pointers nor with object oriented programming.

AutoScale mode allows developing for different screen resolution having the language taking care of the adjustments needed in UI appearance.

Example code

Here is an example of the language:

Code snippet that displays a message box "Hello, World!" as the application starts, without any forms being loaded:

Sub App_Start
MsgBox ("Hello, World!")
End Sub

Libraries

Based on Microsoft's .NET technology, Basic4ppc supports .NET .DLLs with some minor adjustments. This allowed users to create a lot of open-source libraries, downloadable at the Basic4ppc forum, usually with complete source code. As with many other programming languages, additional libraries include most of the real-world language functionality. Additional libraries cover subjects such as graphics
