// should be treated as column names:
csv.HasColumnNames = True

Dim success As Boolean
success = csv.LoadFile("sample.csv")
If (success <> True) Then
    System.DebugLog(csv.LastErrorText)
    Return
End If

// Display the column names:
Dim i As Int32
Dim colName As String
Dim idx As Int32
For i = 0 To csv.NumColumns - 1
    colName = csv.GetColumnName(i)
    System.DebugLog(Str(i) + ": " + colName)

    // The following line demonstrates to to get the column
    // index given a column name:
    idx = csv.GetIndex(colName)
