Declare Procedure Method
The Declare Procedure method declares a procedure in a module or in a dynamic link library (DLL). The value it returns depends on one of the following formats that you use:
Format A. It does not return a value.
Format B. A value of the funcType type. You can use this value in an expression.
For more information about the format and arguments that you can use with this method, see Declaring a Procedure.
Format A
Declare Sub name [(argument [As type])]
Declare Function name [(argument [As type])] [As funcType]
The following table describes the arguments that you can use with this method.
| Argument | Description |
|---|---|
name |
The name of the subroutine or function that this method declares. |
argument |
The argument that this method passes. A comma separates each argument. |
type |
The data type of the arguments. |

Example
The following example declares a function that the main subroutine subsequently calls. This function only sets the return value to 1:
(general) (declarations)
Option Explicit
Declare Function SVB_exfunction()
Function SVB_exfunction()
SVB_exfunction = 1
End Function
Sub Button_Click
Dim y as Integer
Call SVB_exfunction
y = SVB_exfunction
End Sub
