How can you validate user input in Avaloq Script?

Validating user input in Avaloq Script is primarily accomplished by using functions and conditional statements. This approach allows developers to implement custom logic that checks input values against specific criteria, such as format, range, and compatibility with expected data types.

By utilizing functions, developers can encapsulate validation logic, making it reusable and easier to maintain. Conditional statements play a crucial role, as they enable the script to execute different actions based on the results of the validation checks. For instance, if an input does not satisfy a certain condition, the script can prompt the user to correct it or handle the error accordingly.

The other approaches mentioned don't offer the flexibility and control needed for comprehensive input validation. Direct comparison to stored values, while valid in specific scenarios, does not accommodate more complex validation logic. Automatic validation through imported libraries could lead to over-reliance on external code without understanding the specifics of user requirements. Predefined global constants serve their own purpose but do not actively validate input data. Hence, using functions and conditional statements stands out as the most effective method for ensuring user inputs are valid in Avaloq Script.
