Examples:
Sub ExampleExit
Dim sReturn As String
Dim sListArray(10) As String
Dim siStep As Single
For siStep = 0 To 10 ' Fyll tabellen med testdata
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
' Linsearch søkjer ei TextArray:sList() etter eit TextEntry:
' Returverdien er indeksen for oppføringa eller 0 (Null)
For iCount=1 To Ubound( sList() )
If sList( iCount ) = sItem Then
Exit For ' sItem funne
End If
Next iCount
If iCount = Ubound( sList() ) Then iCount = 0
LinSearch = iCount
End Function
