How do variable scopes work in Avaloq Script?

• A. Variables declared within a function are accessible globally
• B. Variables declared globally are accessible only within their file
• C. Variables can only be public or private
• D. Variables declared inside a block are only accessible within that block

Answer: (D)

In Avaloq Script, variable scope plays a crucial role in determining where a variable can be accessed and utilized in the code. The correct choice highlights that variables declared inside a block—such as within a loop, conditional statement, or a function—are only accessible within that specific block. This local scope helps maintain encapsulation, which is important for avoiding unintended interactions with other parts of the code. By limiting variable accessibility to the block in which they are defined, developers can prevent naming collisions and have greater control over the use of variables. It fosters better code organization and reduces the chances of errors that can arise from unintended variable reuse in different parts of the program. In contrast, the other options misrepresent how variable scopes function in Avaloq Script. For example, global variables are accessible throughout the entire codebase, not limited to their defining file, and variables cannot simply be categorized as public or private without context. Thus, recognizing the significance of block scope is essential for effective programming in Avaloq Script.
