Stored procedures
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.
