Subroutines
Save
Subroutines are a fundamental concept in computer programming, and understanding them is essential for anyone who wants to write efficient and maintainable code. A subroutine is a self-contained block of code that can be called from multiple places in a program. This allows programmers to reuse code and avoid duplication, which can save time and reduce the risk of errors.
Why Learn Subroutines
There are many reasons why you might want to learn about subroutines. Some of the most common reasons include:
- Reusability: Subroutines can be used to reuse code, which can save time and reduce the risk of errors.
- Modularity: Subroutines can help to make your code more modular, which can make it easier to read and maintain.
- Encapsulation: Subroutines can be used to encapsulate related code, which can help to improve the organization of your code.
- Testing: Subroutines can be easily tested, which can help to ensure that your code is working correctly.

Online Courses
There are many online courses available that can teach you about subroutines. These courses can be a great way to learn at your own pace and in your own time.
Some of the most popular online courses that teach about subroutines include:
- Excel/VBA for Creative Problem Solving, Part 1
- IBM z/OS Rexx Programming
- Design a CPU 2
These courses can teach you the basics of subroutines, as well as more advanced concepts such as recursion and dynamic programming. They can also provide you with hands-on experience writing and using subroutines in your own code.
Are Online Courses Enough?
Whether or not online courses are enough to fully understand subroutines depends on a number of factors, including your learning style, your prior experience with programming, and the specific course you choose.
If you are a complete beginner to programming, you may find it helpful to take an online course that covers the basics of programming before you start learning about subroutines. This will give you a solid foundation in the concepts of programming, which will make it easier to learn about subroutines.
If you have some experience with programming, you may be able to learn about subroutines by taking an online course or reading a book. However, you may find it helpful to supplement your learning with hands-on experience writing and using subroutines in your own code.
No matter how you choose to learn about subroutines, it is important to practice writing and using them in your own code. This will help you to develop a deeper understanding of how subroutines work and how to use them effectively.
