Beginner's All-purpose Symbolic Instruction Code (BASIC) Programming Language
The programming world, is not an easy place to navigate, because you have to always improve your skills and learn new information all the time. If you intend on developing an amazing application, you have to do the hard work, you won't just create something amazing, by sitting on the sidelines and then that's it. If you are not upgrading your programming skills and gaining more and more knowledge, you will never develop something that is worth using.
Oh nooo, you will most often, find yourselves struggling to build and develop, an amazing software or web application, that is both useful and valuable to your users; which can also bring change to your life.
If you, however, don't care to build a state of the art program, then by all means, go ahead and develop whatever you want, whatever comes to mind, using whatever tools and resources, that are available to you, go ahead and do a sloppy job, and you'll see how much fun you would have.
I am being sarcastic, if you don’t build a state of the art application, your newly built application will become a nightmare to you, and you may never want to develop a software, ever in your life.
When you embark, on building your application, you have to go back to basics, always go back to your basic skills, never get ahead of yourselves, or you will miss very important steps, which are necessary for you, to become a great programmer, and to be able to build a great software or web application.
In today's article we are going to talk about BASIC, a programming language that is only being used, by experienced programmers who know, what they are doing.
BASIC stands for Beginner's All-purpose Symbolic Instruction Code. Although BASIC is very simple, it has nothing to do, with a beginner’s programming language.
BASIC has been used by more programmers, than any other programming language, in the history of programming and coding.
Learning BASIC, will allow you to realize, that computer languages, are there to help you establish a communication with your computer.
Learning BASIC as one of your computer skills, will help you to not only create great software, but it will also, polish your skills, and will help you become a better programmer to your clients.
You will gain a better understanding, about coding and programming, as you develop your applications, using BASIC.
Windows operating systems, are suited to support BASIC, therefore, if you want to start on your software or application development using BASIC, remember that you will more often than not, will rely on windows operating system, to develop that software or web application, and make it become a reality.
Remember though, set your working environment right, the first time; the very first time, you set it up, so that you don't have to start from scratch, if your working environment is not set up right.
If you do start all over again, because you didn't set up your system the right way, the very first time, then you will always finish your setting up your development environment faster; assuming you already have enough experience and knowledge, about your software or web application, the first time you started coding, the wrong way.
The prior knowledge and experience, about your web application or software, you gained during your first try, should propel you, to work at a faster rate, and finish your development in no time, the second time around.
Alright, let's get back to the fact of the matter, BASIC; in order for you to be able to program with BASIC, you would use a CONSOLE TERMINAL, to be able to execute your programs using BASIC.
Also, at the beginning of each of your lines of code, you would put a number in front of them, in order for your computer, to be able identify that line, which is also called a statement.
The statements that you write for your software or web applications, are the set of instructions, which your application would use, to perform the tasks, you commanded it to do.
In BASIC, you can also type your statements, in any order, because the computer, would read the line numbers, which you give to each of your statements.
Because we are talking about BASIC, your computer has the ability, to sort out the statements of your programs, and orders them, according to the numbers you have given to each one of those statements, before your computer can execute your program, or web application.
BASIC, also has different types of statements, and are denoted by a word, which follows the number, at the beginning of statements.
Another feature of BASIC, is that each of the words or letters, which follow the number, is written in upper case letter as well.
You also have to do special things, when you write statements in BASIC, in order to take care of some letter words, such as uppercase O and I, which your computer can mistake for other things, such as zero and one.
Also, in the BASIC programming language, spaces can be omitted, or you can use them, it doesn't really matter, unless you want to print something out to the screen.
When you are printing something to the screen to translate a message, to your users, then a space would be necessary, so that your user, is able to understand what it is, that you are trying to convey on your application.
When you create a software using the BASIC language, you may use the READ statement after the number, which is at the beginning of each statement of your program.
Remember by the way, that each statement of your program in BASIC, must start with a number, so that your computer may be able to order them, before it is able to execute your program.
The READ statement, causes your computer to give values, to any variable that is listed after the READ statements.
The values that these variables receive, are given according to the DATA statement found on your program.
The DATA statement, found on your program is there, to hold the values, which are given to your variables, defined in the READ statement.
BASIC, also has a LET statement, which is used, to compute a condition, and assign the results of that condition, to another variable.
The conditions used in a LET statement, can range from being very simple, to being very complex, depending on what it is, you want your software to accomplish.
You may also use parenthesis, in your conditional statements, to order a computation that you may want your application to solve.
When you use variables in BASIC, you can only use a capital letter, followed by a single digit.
BASIC, also contains an END statement, which denotes the end of the program; you have to always give the END statement, the highest number on your program, so that your computer doesn’t throw an error. Remember that you have to number each of the statements of your program, so that your computer can sequentially execute them.
Variables in BASIC, can only be assigned with the LET or READ/DATA statements, and when you name them, be aware that the upper case I and the number 1 or upper case O and the number 0, may cause you some trouble, so be very aware of that, when you name your variables.
In BASIC, just as in an ordinary mathematical formula, expressions are formed, by combining variables and numbers, with arithmetic operations and parenthesis. So if you know, how to form simple arithmetic operations, then you will be able to form them in BASIC, easily.
In BASIC, you will often, require parenthesis, to present expressions, because expressions must be in one line.
BASIC, is a simple, but yet powerful language, that you can use, to create really cool and state of the art software and web applications.
BASIC was developed in 1960, by John G. Kemeny and Thomas E. Kurtz, at Dartmouth College.
Since its creation, BASIC has become one of the most popular languages used today, because it is easy to learn, and simple to use, but at the same time, it is very powerful and can help you accomplish, many things in the cyber world.
You can use BASIC, in different modes, one of these modes is the immediate mode, which allows your computer to perform, each statement you type, as soon as you press enter, on the keyboard.
While you program in this mode, you'll be able to use the PRINT statement, to print anything you want to the screen.
You will also be able to use, the CALL SOUND statement, which helps you produce sounds over a range of frequencies.
Also the CALL CLEAR statement will be available to you, and it will help you clear your screen, and start all over again, in case you just have a bunch of statements, on your screen and, can’t make sense of them.
Also, if you would like to have graphic capabilities with BASIC, you can use the CALL VCHAR and the CALL HCHAR statements, which help you, draw a line of characters on your screen.
BASIC also has the NEW statement, which tells your computer to delete the program you just developed, from its hard-drive and memory.
Don't make the mistake, of confusing this statement, with the CLEAR statement, which only clears the screen.
Also BASIC contains, the RUN statement, which tells your computer to run the program that you have created.
Another statement of BASIC, is the LIST statement, which will show you a list of BASIC programs, which you have saved on your computer. The feature we just mentioned above are just some of the things, you will find in BASIC.
The only way that you will be able to fully grasp BASIC, is if you experience this programming language itself.
Remember to continue to do your research first though, and don't just jump into programming, you will not have a good time, if you just start to program and don't know what you are doing.
Also remember that, your software, should solve a problem, and bring real value to the intended users, if it doesn't accomplish these things, then you are going to need to go back to the drawing board and formulate a better idea, don’t waste your time just writing code, just because you may think it’s fun, to just write code.
Writing code, is not a fun thing to do, you have to find a purpose for your application, before you start to develop something, and you need to know, what you are doing, when you develop your program.
When you develop a software or a web application, which has a valuable purpose in real life, you will also have a better experience and you will appreciate the work and effort you put into developing your application.
Above all the programming skills, which you will acquire while developing your application, you will also be very clear, about the purpose of your program and what it is that it is supposed to do for the intended people.
I am sure you'll be able to rapidly come up with an idea that is both valuable to your users first and to you as well. Remember, that you are also competing with many people, who are becoming as computer savvy as you are, and they may, create your idea but better.
