What keyword is used to define a constant in Avaloq Script?

• A. The 'final' keyword
• B. The 'constant' keyword
• C. The 'immutable' keyword
• D. The 'fixed' keyword

Answer: (B)

In Avaloq Script, the correct keyword used to define a constant is the 'constant' keyword. This keyword allows developers to declare variables that are meant to remain unchanged throughout the program's execution. Once a constant is assigned a value, that value cannot be modified, which is particularly useful for preventing accidental changes to critical values in the script, maintaining the integrity of data. Understanding how to use constants effectively can lead to more readable and maintainable code, as it clarifies which values are invariant. In contrast, the other keywords mentioned are not used in this context within Avaloq Script. For example, 'final' is commonly associated with finalizing classes or methods in other programming contexts, while 'immutable' refers to the property of an object that cannot be changed after it is created, and 'fixed' does not have a relevant application in defining constants within this scripting language. Thus, they do not serve the purpose of declaring constants in Avaloq Script.
