Return Without GoSub in Excel VBA – A Game Changer!

Sharing is caring!

Did you know that using the GoSub programming practice in Excel VBA can lead to code that is 2.05 times faster than using a Function? That’s right! In certain scenarios, GoSub can provide significant performance advantages in VBA programming.

In this article, we will explore the advantages and disadvantages of using GoSub in VBA, as well as the ongoing debate surrounding its usage. We will also conduct a performance comparison between GoSub and Functions in VBA, and discuss the differences in GoSub’s performance between VBA and VB6. So, if you’re ready to dive into the world of GoSub and discover its potential in Excel VBA, read on!

The Debate Around Using GoSub in VBA

When it comes to using GoSub in VBA programming, opinions are divided. Some programmers argue against its use, citing drawbacks such as spaghetti code and the inability to return a value like a Function. On the other hand, there are those who believe that GoSub has its place in VBA programming, especially when dealing with repetitive code within a procedure.

One potential benefit of using GoSub in VBA is that it can lead to more concise and organized code. Line labels can be easily located and followed with proper commenting, making the code easier to read and maintain. However, it is important to note that GoSub is not commonly used in modern programming languages and may not be familiar to younger programmers.

The debate surrounding the use of GoSub in VBA ultimately boils down to personal preference and the specific requirements of the programming task at hand. Some programmers may find value in using GoSub for its potential organizational benefits, while others may prefer to stick with more traditional Subs and Functions. Ultimately, the decision to use GoSub in VBA programming should be based on a careful consideration of the benefits and drawbacks, as well as the overall goals and constraints of the project.

Performance Comparison: GoSub vs Function in VBA

In order to determine the performance differences between using GoSub and Function in VBA, a comprehensive performance test was conducted. The objective of this test was to measure the execution time of code written with GoSub versus code written with a Function, and analyze their relative advantages in terms of performance.

The test involved running the code 10,000 times and measuring the time taken in milliseconds. This ensured a sufficient sample size for accurate analysis and comparison.

The results of the performance test revealed that the code written with GoSub was 2.05 times faster than the code written with a Function in VBA. This indicates a notable advantage for GoSub in terms of execution speed.

However, it is important to consider the specific circumstances and requirements of the programming task at hand when deciding whether to use GoSub or a Function for improved performance. While GoSub demonstrates superior performance in the test scenario, it should be noted that when the code was compiled to native machine code, the GoSub code was over 3 times slower than the Function code. This suggests that the performance advantages of GoSub may be diminished or even reversed in compiled versions of VBA.

Ultimately, GoSub can be a valuable tool in VBA programming, providing faster execution in certain scenarios. Its advantages include not needing to push/pop variables from the stack and not having to initialize and destroy local variables on each call, resulting in more efficient code execution. However, it is crucial to assess the specific requirements and constraints of each programming task to determine the most suitable approach for improved performance.

It is worth noting that while GoSub can offer performance benefits in VBA, it may not always provide the best overall performance when compared to traditional Subs and Functions. Therefore, careful consideration and experimentation are recommended when deciding whether to employ GoSub in VBA programming.

GoSub in VB6: A Different Story

When it comes to the performance of GoSub in VB6, a predecessor to VBA, it was tested and compared to its counterpart in VBA. The results revealed some interesting insights into the efficiency of GoSub in these two programming languages.

In terms of speed, the tests showed that GoSub in VB6 outperformed GoSub in VBA. Specifically, when the code was compiled to machine code in VB6, the performance of GoSub was significantly faster compared to VBA, especially when compared to code compiled to p-code in VB6.

However, it’s important to note that both VBA and VB6 exhibited superior performance when traditional Subs and Functions were used instead of GoSub. While GoSub may have a place in certain scenarios in VB6 programming, it is generally recommended to opt for Subs and Functions to ensure improved performance.

Performance Comparison of GoSub in VB6 and VBA

As seen in the table above, regardless of the language, traditional Subs and Functions consistently showcased superior performance compared to GoSub. While GoSub in VB6 may offer faster execution, it is important to consider the overall performance implications and opt for Subs and Functions whenever possible.

Throughout the performance comparison between GoSub in VB6 and VBA, it is evident that GoSub may provide certain advantages in terms of speed and execution time in VB6. However, it is essential to consider the larger context and prioritize the use of traditional Subs and Functions to achieve optimal performance in both VB6 and VBA programming.

Conclusion and Words of Encouragement

In conclusion, utilizing the GoSub feature in VBA programming can bring numerous benefits to your coding endeavors. One notable advantage is the potential for faster execution in specific scenarios, allowing you to optimize the performance of your code. Additionally, incorporating GoSub can enhance the structure and organization of your code, resulting in a more concise and manageable programming experience.

However, it is vital to exercise proper judgment when deciding to employ GoSub in your VBA projects. Carefully consider the specific requirements of the task at hand and evaluate whether GoSub aligns with the project objectives and constraints. While GoSub can be a powerful tool, it should be used judiciously and not as a catch-all solution.

Furthermore, keep in mind that the performance implications of using GoSub may vary depending on the programming language and its compilation process. While it can deliver impressive execution speed within VBA, the story may differ in compiled versions such as VB6, where traditional Subs and Functions may offer improved performance.

As we conclude this article, let it serve as a reminder and inspiration for aspiring VBA programmers. Explore different techniques, experiment with new approaches, and expand your coding repertoire. Embrace the journey of enhancing your skills and achieving success in your projects. Remember, the end result is well worth the effort invested. Happy coding!
