Call Statement

Transfers the control of the program to a subroutine, a function, or a procedure of a Dynamic Link Library (DLL). The keyword, type and number of parameters is dependent on the routine that is being called.


Call Statement diagram

[Call] name [(] [param :=] value, ... [)]


name: Name of the subroutine, the function, or the DLL that you want to call

param: Keyword parameter name to pass to the routine, followed by its value. The name must match the routine declaration. Keywords are optional and can be used in any order.

value: Positional parameter value. The type is dependent on the routine that is being called


При смешивании позиционных и ключевых параметров убедитесь, что позиционные параметры соответствуют обычному порядку объявления.


When a function is used as an expression, enclosing parameters with brackets becomes necessary. Using a Declare statement is compulsory prior to call a DLL.


Sub ExampleCall
    Dim value As String
    value = "LibreOffice"
    Call aRoutine value
    aRoutine text := value
End Sub

Sub aRoutine (text as String)
    Msgbox text
End Sub
