QBasic (QuickBASIC)

QBasic (Microsoft QuickBASIC or abbreviated as QB) is a fairly simple and convenient integrated development environment and compiler developed in the second half of the 1980s by Microsoft's BASIC (Basic) programming language.

There are two varieties of BASIC dialect, for DOS and Mac OS. For its time, the programming language Basic was quite perfect: it supported several types of users, structural programming, supported graphic and disk operations, versions older than 2.0 work with a visual text editor.

There are several versions of the integrated QuickBASIC environment - QuickBASIC 4.5, QBasic, QBasic 7.1 PDS, QuickBASIC 1.0 RU and QB64. QBasic version is a shortened version of the final release of QuickBASIC 4.5 for MS-DOS older than version 5 and various versions of Windows (including 7.8.10 64-bit) in DOS emulation mode. The program is used as an interpreter of a simple programming language at the initial levels of education.

QBasic provides an easy and convenient environment for beginners to learn and implement the basics of programming language.

The basis of the truncated QBasic is the Intelligent Editor and the Compiler Type Interpreter. It pre-composes and compiles the program into the original pseudocode and then performs it. After debugging the created program, the user can create an executable .exe file using the real compiler and the environment compiler from QuickBASIC 4.5 or other more complete versions.

Programming on QBasic is easy and pleasant. The BASIC programming environment is perfect for simple calculation and teamwork. Programming environment is not suitable for creating multi-module programs (you can not load previously created modules), the program must be written from beginning to end.
