Learn QBASIC with Real Code Examples

Procedural programming paradigm

Sequential execution of statements

Subroutines for code modularity

Event-driven programming is minimal

IDE interprets and executes code line by line

User writes code in IDE

Interpreter executes statements sequentially

Subroutines executed when called

Output displayed on screen or written to file

Program flow controlled via loops and conditionals

Procedural linear execution

Modular code via subroutines

Sequential I/O operations

Limited event-driven capability

Simple graphics rendering commands

Text-based games

Educational programming exercises

Simple DOS utilities

Demonstration of algorithms

Basic graphics demos

Beginner-friendly syntax

Interactive IDE for immediate feedback

Procedural programming focus

Lightweight and easy to set up

Encourage learning programming logic and structure

Programs limited to single-user execution

Memory constrained by DOS limits

No native concurrency support

Optimize loops and logic for efficiency

Best for small programs and educational projects

Port code to modern BASIC variants or Python

Refactor DOS-specific graphics or I/O

Replace file handling with modern equivalents

Test program logic in new environment

Gradually migrate educational exercises
