[Compilador] Diferencia BY REFERENCE, BY VALUE, BY CONTENT

[Kuk]

Amigos, información útil:

❞ BY REFERENCE passes the address of an item BY VALUE passes the value of the item directly. Therefore, as with the BY CONTENT specification, the BY VALUE specification does not cause the content of the parameter to be changed in the calling program, even when the content of the corresponding parameter in the called program is changed. Note that the coding in the called C program varies depending on whether it receives an address or a value. Remarks: If the BY specification is omitted, BY REFERENCE is assumed.
