As we saw in the previous topic in this chapter, functions and function parameters in C/SIDE are not declared directly in the code editor. Instead, they are entered in a tabular view presented in a separate editor. This is also true for variables; we do not describe variables in C/AL code, but access the variable declaration through the C/AL Locals and C/AL Globals windows.
Declaring variables – variable scope
Local variables
To illustrate the declaration and use of local variables, we will implement a simple algorithm comparing two strings to find the editorial distance, or Levenshtein distance. This distance is a measure of similarity between strings that is often used in various text processing systems to suggest...
