# Sub Statement

Определяет подпрограмму.

### Синтаксис:

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

### Параметры:

name: Name of the subroutine.

arguments: Optional parameters that you want to pass to the subroutine.

##### argument fragment

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

##### Параметры

Optional: The argument is not mandatory.

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: Type declaration character.

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.

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

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

##### typename fragment

          {Boolean|Byte|Currency|Date|Double|Integer|Long|Object|Single|String|Variant}

##### char fragment

          { % | & | ! | # | $ | @ }

### Примеры:

    Sub ExampleExit
    Dim sReturn As String
    Dim sListArray(10) As String
    Dim siStep As Single
        For siStep = 0 to 10 REM Заполнение массива контрольными данными
            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
    REM Linsearch ищет TextArray:sList() для TextEntry:
    REM Возвращаемое значение - индекс записи или 0 (Null)
        For iCount=1 To Ubound( sList() )
            If sList( iCount ) = sItem Then
                Exit for REM sItem обнаружена
            End If
        Next iCount
        If iCount = Ubound( sList() ) Then iCount = 0
        LinSearch = iCount
    End Function
