[Private | Public] Sub name[(argument1 [As typename][, argument2[char][,...]])]
    ' instrucciones
    [Exit Sub]
    ' instrucciones
End Sub

Par谩metros:

nombre: el nombre de la subrutina

argumentos: par谩metros opcionales que pasar a la subrutina.

      {[Optional [ByRef|ByVal]]|ParamArray} argument {{As typename|char}[ = expression]|[()]As Variant}
    
Par谩metros

Optional: el argumento no es obligatorio.

ByRef: The argument is passed by reference. ByRef is the default.

ByVal: The argument is passed by value. Its value can be modified by the called routine.

char: car谩cter de declaraci贸n del Tipo.

typename: Primitive data type name. Library or module defined types can also be specified.

= expression: Specify a default value for the argument, matching its declared type. Optional is necessary for each argument specifying a default value.

ParamArray: Use ParamArray when the number of parameters is undetermined. A typical scenario is that of a Calc user-defined function. Using ParamArray should be limited to the last argument of a routine.

tip

UsingParamArray or = expression require Option Compatible to be placed before the executable program code in a module.


warning

When using Option VBASupport 1, Optional arguments with no default value (= expression) are initialized according to their data type, except if Variant.

Ejemplos:


Sub ExampleExit
Dim sReturn As String
Dim sListArray(10) As String
Dim siStep As Single
    For siPaso = 0 to 10 ' Rellenar matriz con datos de prueba
        sListArray(siStep) = chr$(siStep + 65)
        MsgBox sListArray(siStep)
    Next siStep
    sReturn = LinSearch(sListArray(), "B")
    Print sReturn
End Sub
 
Function LinSearch( sList(), sItem As String ) As Integer
Dim iCount As Integer
' BuscaLin busca en MatrizTexto:sLista() una EntradaTexto:
' El valor de retorno es el 铆ndice de la entrada o 0 (Nulo)
    For iCount=1 To Ubound( sList() )
        If sList( iCount ) = sItem Then
            Exit For ' sItem encontrado
        End If
    Next iCount
    If iCount = Ubound( sList() ) Then iCount = 0
    LinSearch = iCount
End Function
