The KBasic Manual – A Quick Reference Guide for the Development of KBasic Applications
Then try out the examples in this manual. This manual is not meant to be a detailed or comprehensive reference manual. The principal purpose of this manual is to act as a quick and practical reference while you are programming.
Here you will find a complete and detailed listing of all objects, their events and procedures, methods and characteristics as well as a complete reference of all operators and commands.
Apart from precise syntax definitions, you will also find a detailed explanation of the available parameters in each case. For the less experienced KBasic programmer, this manual includes an extensive introduction to the KBasic programming language with numerous examples of the most important elements of the language, including the more complex object oriented aspects of KBasic.
This manual was written for both the absolute beginner and for the person with some background knowledge in BASIC. Even experienced Visual Basic developers should feel very comfortable with this manual.
I am very grateful to all the people who helped me complete this manual. Special thanks to Nadja, my girlfriend, and to everyone who bought KBasic Professional, including all those people who supported me in other ways.
A big thanks also to my parents. Bernd Noetscher is a software developer and the main developer of the KBasic programming language. In his spare time he goes dancing, reads many books, and plays the piano. He is also interested in theatre and cinema. His private website is hosted at www. Nadja Hepp for proofreading this manual and for beta testing. Thanks to everyone on the Internet who submitted corrections and suggestions, especially Christopher Scott Wyatt and his wife Susan; you have been tremendously helpful in improving the quality of this manual and I could not have done it without you.
Please help me improve this manual. To do this, we need your help. As the reader, you are potentially a most important contributor and valued critic of this manual. We respect your opinion and would like to know what improvements we could make. We would also like to get positive comments, too.
In addition, if you find any mistakes in the text or errors in the example programs, please send an e-mail to info kbasic. Bear in mind that due to the high volume of mail we receive, we may not be able to reply to every message we get. Thank you very much. We cannot help you with technical problems related to the topics covered in this manual. KBasic was developed by KBasic Software and has aroused much interest on the Internet among businesses and developers. In response, we documented this exciting new technology with a set of new manuals.
This series of manuals covers language references, introductory volumes, API references, and advanced topics on programming in KBasic, such as databases and networks.
In this manual, normal text appears in a regular font. Here is an example: Visit the KBasic website at http: Also, search the Internet using Google at http: If you are not a newcomer to programming computers, you may want to skip this section and go straight to the introduction on the KBasic programming language, instead.
Have you ever wanted to know how a computer program works?
If so, there might be a computer programmer somewhere inside you waiting to get out. As a beginner, you may have found computer programming somewhat intimidating and possibly downright frightening. You have probably heard a lot about KBasic. In fact, you may have already downloaded it and played around with the IDE and some manuual the sample programs, and have your own ideas about what a program is and how it works.
Now, you want to create your own KBasic programs. But, before we get started, you ought to have a solid understanding of what programming kbasci all about.
So, we encourage you to read this manial thoroughly, to better aquaint yourself with the fundamental concepts involved in programming computers. It will be worth it! The computer programming world has a well-kept secret. You will probably find this secret hard to believe. A computer can do absolutely nothing on its own. Computers without programmers are useless. Computers can do only what they are told to do. This means computers can only do tasks that humans already know how to do.
So, why are computers so great? Computers may not be smart, but they can perform endless calculations in seconds and easily do repetitive tasks over and over without making any mistakes.
Programmers also known as developersare the people who tell computers what to do. For example, when kbasid sit yourself down in front of a word processor and write a letter, you are indirectly giving the computer commands to execute or act upon. You are using the commands contained within the word processing program which were written by a programmer.
The computer program actually tells the computer what to do. The bottom line is this: Why would you want ibasic learn to program? There are many reasons for doing this. For example, you may want to:. These are all good reasons, and you might even have a better one for learning to program. But, manuxl your reason, once you start programming, you will find it can be fascinating, interesting, and addictive. A computer program is a list of instructions or commands lbasic a computer what to do.
The computer follows these instructions, one-by-one, until it reaches the end of the program. Each line in a computer mankal is usually a single command that the computer must do. And each command normally does only one small task, such as printing a name on the screen or adding a few numbers together. When you put hundreds, thousands, or even hundreds of thousands of these commands together, your computer can do great things: As you will see in the next paragraph, computer programs are written in a programming language.
There are many different programming languages to choose from. Computers do not understand German, English or any other human language. Computers understand one thing only, machine language or machine code, which is entirely composed of ones and zeroes from the binary numeral system.
Programming languages like BASIC allow people to write programs in an English-like language, which is mmanual translated into machine language by another program called an interpreter or compiler. This is done so that the computer can understand the English-like program in its own language — much like someone translating a foreign language for you so you can understand what the other person is saying to you in your own language.
KBasic programs are a dialect of the BASIC computer mamual that was developed to help make it easier for people to program computers. KBasic uses words and symbols which are used to represent the binary instructions used in machine language. These words and symbols are kbaasic simpler for programmers to understand and remember.
As a programmer, it is so much easier to use a command like Majual instead of a binary-coded instruction likefor example, which is long and difficult kbasiic remember.
Instead of thinking like a machine in manjal binary numbers, you can think like a human being using words and symbols to construct your program. Even KBasic uses this spelling. However, the word BASIC actually started out as an acronym, which is why you also see the name spelled in all capital letters. When you run KBasic, you are also loading a compiler. A compiler is a special program that takes the words and symbols from a KBasic program and translates them into machine language manuzl the computer can understand.
However, all computer languages have one thing in common: Since that time, numerous versions or dialects of this language have been written, of which KBasic is only one of them. Some computer languages, including some types of BASIC, convert a program to machine language one line at a time as the program is running.
In either case, all programming languages must be converted to machine language in order for the computer to understand the program. A compiler changes your program into an executable file that can be run directly by a computer. An executable program is actually a machine language program that is ready for your computer to read and understand.
With few exceptions, most computer mnual languages make use of a compiler. However, in some cases, hybrid compiler-interpreters are used by some languages, such as Java and KBasic, which are a mix of compiler and interpreter.
Now that you know something about kbasiv programs, how do you go about writing one? Creating a computer program is fairly easy, although it can be a long process when writing lengthy programs. Writing a KBasic program requires development steps similar to those you use when writing a report. The following list outlines possible steps you can take to write your own programs:.
Most of the steps in the programming process are repeated over and over as errors are discovered and corrected.
