Transfers control to a
Sub, or dynamic-link library (DLL) procedure.
[ Call ] procedureName [ (argumentList) ]
Required. Name of the procedure to call.
Optional. List of variables or expressions representing arguments that are passed to the procedure when it is called. Multiple arguments are separated by commas. If you include
argumentList, you must enclose it in parentheses.
You can use the
Call keyword when you call a procedure. For most procedure calls, you aren’t required to use this keyword.
You typically use the
Call keyword when the called expression doesn’t start with an identifier. Use of the
Call keyword for other uses isn’t recommended.
If the procedure returns a value, the
Call statement discards it.
The following code shows two examples where the
Call keyword is necessary to call a procedure. In both examples, the called expression doesn't start with an identifier.
Sub TestCall() Call (Sub() Console.Write("Hello"))() Call New TheClass().ShowText() End Sub Class TheClass Public Sub ShowText() Console.Write(" World") End Sub End Class
