Mandatory or optional parameters?

The parameters received in the procedure can be mandatory or optional parameters. A mandatory parameter must be filled during the call to the procedure while an optional parameter can be omitted: in this case, it will take the default value defined when declaring the procedure parameters.

	Remark	When declaring a procedure, the optional parameters are the last parameters (they are always specified after all mandatory parameters).

In the following example, the Multiplication procedure uses an optional parameter, Nb2. This optional parameter is indicated after the mandatory parameters, by specifying its default value. In this example, the default value of optional parameter is set to 10.

PROCEDURE Multiplication(Nb1 is int, Nb2 is int=10)
MyResult is int
MyResult = Nb1 * Nb2
RESULT MyResult

The code used to call the procedure is as follows:

res is int
res = Multiplication(6)
// Res is equal to 60
