KBasic is a powerful programming language, which is simply intuitive and easy to learn. It is a new programming language, a further BASIC dialect and is related. DroidBasic_General Manual KBasic Software started development on DroidBasic in (C)opyright Bernd Noetscher’s KBasic Software – New set of manuals about KBasic KBasic was developed by KBasic Software and has aroused much interest in the Internet. If we have made any mistakes.

Keep in mind the arguments are passed to the procedure in the order in which they appear in the procedure call.
Normal procedures are only called explicitly. If you do not, it is by default an instance-variable. The default modifier is ‘Public. Select in the binary creator: Storing does not save the values on disk but saves them in memory because you need the values only when running your program. See your Mac OS X documentation and installation for details.

After stopping your program, kbasid variables even objects are deleted. Create a class, which contains a methods, which is useful for your forms. KBasic demands that every procedure that can raise an exception must define a exception with a ‘Throw’-statement in its declaration. In specifying a SELECT query, the user specifies a description of the desired result set, but they do not specify what physical operations must be executed to produce that result set.
There are many reasons for doing this. Sometimes, you may want to use an object differently or perform the initialization differently. Address Please feel free to contact us. It is possible not to know the length of an array while coding or you would like to change its size at runtime.
Named arguments are also useful when you use procedures with optional arguments. Variables of type ‘Variant’ can contain strings, dates, time values, boolean values or even numerical values. They can contain keywords, operator, variables, constants or even other expressions.
Methods are procedures or functions of a class. One of the most important characteristics regarding reliability is correct memory management. If a procedure is executed, a variable exists after its ‘Dim’-statement. The following pages cover these language elements.
Syntax Overview about the grammar. Global modules are always present. If the ‘Dim’-statement is used in module scope or class scope, it is treated as a ‘Private’-statement.
Create objects using the special keyword ‘New. The examples in this manual are always indented and formatted.
It is not a toy. It might be useful in some situations. Like Java, KBasic uses references instead of pointers to objects. You can write many statements in one line using a colon: But why should you use KBasic?
A variable is a space in memory used by KBasic to store values so variables are not stored in a file.
On the other end are the fully compiled machine code programming languages. For example, you may want to:. As you will see in the next paragraph, computer programs are written in a programming language. Because line numbers in KBasic programs are now obsolete, you do not have to worry about how to use them. Some properties are only readable. Toolbars KBasic provides an extensive set of toolbars.
This is the principle of graphical user interfaces and event controlled programming. For example, if you have the declaration of a variable named ‘price’ in a procedure, and the same declaration in a module, all uses of this variable in the procedure are related to the local variable ‘price,’ all uses outside the procedure are related to the global variable ‘price.
This may be true in the long run. The order in which the code is executed depends upon the order of the events that occur, which is based upon user actions. To accomplish this, place the underscore character at the end of a line to continue the statement onto the next line. So comments, normally, describe how your program works. Just place a WebView and the right location with flash on a form. Developers in any language always wanted to write bug-free programs, programs that never crash, programs that can deal with any situation with grace and that can recover from unusual situations without causing the user any undue stress.
An event is an action bkasic by an object, e. You can use it for free. SQL keywords fall into several groups. A project is a collection of files that make up your KBasic application.
