;  This example program loads a file (sample.csv)
;  that contains this content:
;  
;  year,color,country,food
;  2001,red,France,cheese

$oCsv = ObjCreate("Chilkat.Csv")

;  Prior to loading the CSV file, indicate that the 1st row
;  should be treated as column names:
$oCsv.HasColumnNames = True

;  Load the CSV records from the file:

$bSuccess = $oCsv.LoadFile("sample.csv")
If ($bSuccess <> True) Then
    ConsoleWrite($oCsv.LastErrorText & @CRLF)
    Exit
EndIf

;  Display the column names:
Local $i
Local $sColName
Local $idx
For $i = 0 To $oCsv.NumColumns - 1
    $sColName = $oCsv.GetColumnName($i)
    ConsoleWrite($i & ": " & $sColName & @CRLF)

    ;  The following line demonstrates to to get the column
    ;  index given a column name:
    $idx = $oCsv.GetIndex($sColName)
    ConsoleWrite($sColName & " is at column index " & $idx & @CRLF)
