QBasic is an interpreter and an Integrated Development Environment (IDE) for the diverse variety of dialects that are present for the BASIC which are based on QuickBASIC. The QBasic is an instant program and run type language. The code that is entered into the developer is compiled into an intermediate representation (IR), and this IR is immediately interpreted on-demand within IDE. The QBasic is similar to QuickBASIC but different from the earlier version of BASIC developed by Microsoft, QBasic is a structured programming language. Microsoft also produced QBasic. Microsoft released the first version of QBasic in 1991. When Microsoft first released QBasic, it was provided with the state-of-the-art IDE, which included a debugger with such features that it was capable of evaluating the expression on the go without storing any data. 

Microsoft released the first versions Windows with built-in QBasic, but now it is not included with Windows, though can still be obtained for usage. Many people tend to use the terms QBasic and QuickBASIC interchangeably, but they are not the same thing. QBasic is not capable of producing executable files (with .exe as an extension), and can only deliver the source code files which are immediately executable (they use the extension .bas) by the built-in QBasic Interpreter. And also QuickBASIC has a wider variety of commands as compared to QBasic.

QBasic is the best language for beginners. It can be used to introduce anyone to programming without knowing how the computer works. The QBasic is a straightforward language and can be used to create simple applications, games and even some simple databases. QBasic also offers commands like SET, CIRCLE, LINE, etc. using which you can draw figures. QBasic also supports sound and can be used to create a sound of a particular frequency through your speakers though it can only produce one sound at a time.

  • a. Program Window – the upper Window in the QBasic IDE, which is titled as 'Untitled' is the Window where you write your programs or codes. The title can be changed when you save the program with '.bas’ extension. You can see the output or run the program by pressing SHIFT + F5.
  • b. Immediate Window – the lower Window is known as the Immediate Window. It is the Window where the test commands and expressions are written for quick testing.
