処理結果を戻り値として返すサブルーチンを定義します。
Sub, Function or Property statements are similar methods, without distinction. They receive parameters by reference allowing them to be modified in return. Collabora Office Basic compiler accepts their respective argument syntax to be used interchangeably.
[Private | Public] Function Name[char] (argument1 [As Type][, argument2[char][,...]]) [As typename]

End Function
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.
Sub ExampleExit
Dim sReturn As String
Dim sListArray(10) As String
Dim siStep As Single
For siStep = 0 to 10 REM 配列にテスト用データを代入
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 はテキスト配列 sList( ) 内に指定文字列を検索
REM 戻り値は、該当するインデックス値ないしゼロ (Null)
For iCount=1 To Ubound( sList() )
If sList( iCount ) = sItem Then
Exit for REM 検索で sItem がヒット
End If
Next iCount
If iCount = Ubound( sList() ) Then iCount = 0
LinSearch = iCount
End Function
