QBasic

Microsoft QuickBasic and QBasic (Quick Beginners All-purpose Symbolic Instruction Code) are very popular programming languages for beginners.
While its lack of power makes it unsuitable for many of today's applications, it is an invaluable learning tool.

This wikibook will cover the usage of QBasic and most of its functions. While most of the text discussed will work under QBasic, that version of the Basic interpreter has limitations and certain advanced commands will only work under QuickBasic.

One of the best Qbasic IDEs (Integrated Development Environment) is QB64. There are certain functions that work only in QB64.
