Why GW-BASIC?
Firstly, we need to understand why we are focusing on GW-BASIC and why it holds significant importance. GW-BASIC is an interpreted language, which forms the basis of modern programming. It is a high-level programming language that introduces the essential elements found in advanced language.
History and Development
The history of GW-BASIC is quite fascinating. Being developed in the 1980s by Microsoft, it is based on BASIC language. The language’s evolution has a profound influence on subsequent programming languages such as Visual Basic. GW-BASIC was seen as a starting point for many budding programmers in the early era of personal computing.
Getting Started with GW-BASIC
To become proficient in GW-BASIC, one must familiarise themselves with the fundamental concepts and command structures of the language. Here are some key points you should understand to kick-start your programming journey.
Understanding GW-BASIC Interface
The GW-BASIC interface is relatively simple and accessible for beginners. Upon accessing the GW-BASIC screen, you would find different command lines for entering your codes, which is characteristic of rudimentary programming interfaces.
Fundamental Programming Concepts in GW-BASIC
Variables and Constants: Similar to modern programming languages, you find two types of data in the GW-BASIC language – Variables and Constants. A variable is an aspect of the program that can change its value, while a constant remains the same throughout the program.
Conditional Statements: GW-BASIC incorporates conditional and looping statements. IF...THEN...ELSE is a crucial conditional statement in GW-BASIC, representing the notion of selection.
Looping Statements: Looping sequences, such as FOR...NEXT and WHILE...WEND, are critical programming elements, giving you the ability to perform a set of commands repeatedly until a specific condition is met.
Data Types: Data types play a crucial role when declaring variables. Familiarizing oneself with GW-BASIC data types such as integer (%), single precision floating point (!), double-precision floating point (#), and string ($) varieties enhances language efficiency.
Benefits of GW-BASIC
While it may seem redundant to learn an outdated language like GW-BASIC, understand that doing so offers various advantages. It provides a solid foundation and improves the way you approach programming, making you adaptable to various programming languages.
1. Fundamental Understanding: GW-BASIC provides a fundamental understanding of how the programming structure works and lays the grounds for you to advance into complex languages.
2. Simplicity: The simplicity of GW-BASIC makes it an appropriate starting point for novice programmers. Its readable code, coupled with a basic development environment, simplifies the learning process.
3. Scalable: Despite its simplicity, GW-BASIC is a highly scalable language. It allows you to build your knowledge and grow with it as you become familiar with more intricate aspects.
Going Beyond GW-BASIC
Once you have mastered GW-BASIC, the journey into complex languages becomes significantly simplistic. The programming principles and operating functionalities learnt in GW-BASIC provide a solid foundation for advanced programming languages, including Python, JavaScript, C++ and more.
In conclusion, understanding GW-BASIC arms you with fundamental programming knowledge that molds you into a versatile and adaptable programmer. It opens doors to an array of opportunities, taking your programming skills to a whole new level.
