ByReference (Property)

In french: ParRéférence

The ByReference property is used to determine if a procedure parameter was passed by reference.

If the parameter was passed by reference, its value can be modified in the procedure code.

Remarks:

This property is equivalent to the ByAddress property.
The concepts "Parameter pass by reference" and "Parameter pass by address" are identical.

This property is available only if the new WLanguage framework is enabled. For more details, see Browser code (WLanguage): Framework 2.

Example

Indice is int = 1
Indice2 is int = 3
Indice3 is int = 4
// Avant l'appel de la procédure, les différentes variables ont leurs valeurs par défaut
AjouteUn(Indice, Indice2, Indice3)
// Après l'appel de la procédure, les variables ont toutes changé de valeur

// -- Declare the procedure
PROCEDURE AddOne(*)
FOR I = 1 _TO_ MyParameters..Count
IF MyParameters[I]..ByReference = True THEN
MyParameters[I] += 1
END
END

Syntax

<Result> = <Parameter used>.ByReference

<Result>: Boolean

True if the parameter was passed by reference,
False otherwise.

<Parameter used>: Character string

Name of the parameter used. This parameter is defined via the MyParameters keyword, by specifying the index of the parameter used. For example: MyParameters[1] to handle the first parameter passed to the procedure.
