CALL function

The CALL function is not a built-in function in Excel. However, in certain programming languages or environments, such as VBA (Visual Basic for Applications) or certain advanced Excel setups, the term “CALL” may refer to invoking a procedure or function.

If you’re looking for something related to Excel functions or how they interact with VBA or external functions, here are some possibilities where “CALL” is relevant:

1. VBA Call Statement:

In VBA (Excel’s programming language), Call is used to invoke a procedure or function. It’s a way of executing a subroutine or function within the code. The Call keyword is not necessary but can be used for clarity, especially when calling a function that requires arguments.

Example:

Sub ExampleProcedure()
    Call MyFunction(5, 10)
End Sub

Function MyFunction(a, b)
    MyFunction = a + b
End Function

In this example, Call is used to invoke MyFunction and pass two arguments (5 and 10) to it.

2. Excel Add-ins or External Calls:

In advanced scenarios, Excel can use the CALL function (via VBA) to invoke functions from external libraries or dynamic link libraries (DLLs). This would typically involve using Windows API calls or COM objects.

3. Excel Formulas for Calling Functions:

If you meant how functions in Excel “call” other functions, then each formula in Excel implicitly calls other functions when you reference them. For example:

• =SUM(A1:A10) calls the SUM function.
• =VLOOKUP(B1, range, 2, FALSE) calls the VLOOKUP function.

But again, there is no direct CALL function in Excel formulas.

Summary:

If you’re referring to invoking functions in Excel or VBA, CALL is specific to VBA for calling subroutines or functions. Excel itself does not have a built-in CALL function in its formulas. If you’re working with VBA or other advanced integrations, Call could be used to trigger custom functions, APIs, or external libraries.
