> ANALYSIS_OF: IBMI_(AS400)_DIFFERENCE_BETWEEN_%SCAN_AND_%CHECK_|__RPGLE_PROGRAMMING_TUTORIAL_|_AS400_FOR_BEGINNERS_
This video tutorial focuses on the differences between the %SCAN and %CHECK built-in functions in RPGLE.
- %SCAN: This function finds the position of a substring within a string. The tutorial covers its syntax, parameters, and practical examples of how to use %SCAN to locate characters or strings efficiently.
- %CHECK: In contrast, %CHECK determines the position of the first character in a string that is not part of a specified set of characters. The video explains its syntax and provides examples to illustrate its usage in validating input or filtering data.
- Practical Applications: The tutorial includes scenarios where each function is best suited, helping programmers understand when to use %SCAN versus %CHECK in their RPGLE code.
- Performance Considerations: The video discusses performance implications when using these functions, guiding programmers on how to write efficient code.
- Common Mistakes: The presenter highlights common pitfalls and mistakes that beginners often make when using these functions, providing tips on how to avoid them.
