# Function Statement

उपकार्यतालिका परिभाषित गर्दछ जसलाई फर्कने प्रकारलाई निर्धारण गर्नलाई अभिव्यक्तिमा प्रयोग गर्न सकिन्छ ।

Sub or Function statements are similar methods, without distinction. They receive parameters by reference allowing them to be modified. LibreOffice Basic compiler accepts their respective syntax to be used interchangeably.

### Syntax:

      [Private | Public] Function Name[char] (argument1 [As Type][, argument2[char][,...]]) [As typename]
              statements
          [Exit Function]
              statements
      End Function

### Parameters:

scope: Function default scope is Public. A Private scope denotes a module internal routine, not intended to be used from other modules.

name: Name of the subroutine to contain the value returned by the function.

arguments: Parameters to be passed to the subroutine.

##### argument fragment

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

##### Parameters

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

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

## Examples:

    Sub ExampleExit
    Dim sReturn As String
    Dim sListArray(10) As String
    Dim siStep As Single
        For siStep = 0 to 10 REM Fill array with test data
            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 Linsearchले पाठ एरे खोज्छ:पाठ प्रविष्टिका लागिsList()
    ' ले फर्काउने मान प्रविष्टि वा ० (निल)को अनुक्रमणिका हो।
        For iCount=1 To Ubound( sList() )
            If sList( iCount ) = sItem Then
                Exit For ' बाट बाहिरिनका लागि sItemभेटाउनुहोस्
            End If
        Next iCount
        If iCount = Ubound( sList() ) Then iCount = 0
        LinSearch = iCount
    End Function
