Parameters of a procedure/function
A procedure can receive parameters. Let's see the different possibilities regarding the management of parameters in WLanguage: - Passing parameters: by reference and value.
By default, when calling a procedure, the parameters are passed by variable (by address or by reference). You also have the ability to pass the parameters by value in WLanguage. - Data type of parameters.
The description of the parameter type is optional. However, you can specify the data types of parameters. - Optional parameters.
Some of the parameters passed to a procedure can be optional parameters. - Variable parameters.
You have the ability to handle the parameters passed to a procedure using a variable number of parameters. - Useful parameters.
You have the ability to manage the parameters declared but not used.
Reminder: - In WLanguage, there is no distinction between the procedures and the functions. The procedures and the functions are managed in the same way.
- You have the ability to create overloaded procedures. For more details, see Prototype overload.
 You have the ability to use named parameters. For more details, see Calling a procedure: Named parameters. - A parameter can correspond to any type of variable. A class instance can be passed as parameter to a procedure.
