QBASIC Programming – Beginner’s Friendly

Computer programming is the process of designing, building and instructing a computer to do a particular computing task. To instruct we need to write codes in some particular programming language that our computer can understand. There are lots of programming languages today, however here we will learn about QBASIC programming language, which is one of the easy to learn languages for beginners.

What is QBasic Programming?

QBasic Program

QBASIC stands for “Quick Beginners All-Purpose Symbolic Instruction Code”. QBASIC was developed by Microsoft Corporation in the year 1991. It is considered to be one of the most easy-to-understand programming languages for beginners. It is suitable for both mathematical and business problem solving and it has been adopted by most of the microcomputers.

QBASIC is a replacement of the GWBASIC (Greg Whitten – BASIC). It was based on the QuickBASIC 4.5 compiler. QBASIC is only compatible with MS-DOS Environment on windows, it usually contains two files: 1.QBASIC.EXE and QBASIC.HLP. These two files help us to debug, edit and execute code in the DOS environment. QBASIC doesn’t produce a .exe file, the files are saved with .bas extension.

History of QBASIC Programming Language

In the year 1985 QuickBASIC was originally released. It was sold on a 5.25” floppy disk. The second version Version 2.0 was released in the year 1986 and it was available in both 5.25” and 3.5” floppy disk. Version 2.0 had a built-in user interface for the comfort of users.

In 1988, the latest version QuickBASIC 4.5 was released it had fixed a few problems from the previous version and was compatible with any computer from 8088 with DOS 2.11 to a Windows XP machine.

And in the year 1991, QBASIC programming language builds as a replacement/upgrade version of the old GW-BASIC. The language was based on QuickBASIC 4.5 but it didn’t have QuickBASIC’s Compiler and also the linker elements. The first version of QBASIC (Version 1.0) was shipped with MS-DOS 5.0 and higher. It was also shipped with Windows 95, Windows NT 3.x, Windows NT 4.0 and Windows 98. It was not shipped with Windows XP but a user can install and use it in their XP machine without any issues.

Starting with QBASIC

QBASIC is an Open- Source software, which means you can use it for free.

The whole QBASIC window is divided into two parts :

Program Window:

It is where people can write/edit their codes. The window is titled as ‘Untitled’ by default which can be changed when the user saves the program into a disk.

Immediate Window:

The Window titled ‘Immediate’  is the Immediate  Window. This window is used as a debugging tool and the outputs of every single command statement can be seen here.
