    // This example program loads a file (sample.csv)
    // that contains this content:
    // 
    // year,color,country,food
    // 2001,red,France,cheese
    // 2005,blue,"United States",hamburger
    // 2008,green,Italy,pasta
    // 1998,orange,Japan,sushi
    // 
    // The first row contains the column names.
    // This file is available at:
    // http://www.chilkatsoft.com/testData/sample.csv

    csv := chilkat.NewCsv()

    // Prior to loading the CSV file, indicate that the 1st row
    // should be treated as column names:
    csv.SetHasColumnNames(true)

    // Load the CSV records from the file:
    var success bool
    success = csv.LoadFile("sample.csv")
    if success != true {
        fmt.Println(csv.LastErrorText())
        csv.DisposeCsv()
        return
    }

    // Display the column names:
    var i int
    var colName *string = new(string)
    var idx int
    for i = 0; i <= csv.NumColumns() - 1; i++ {
        colName = *csv.GetColumnName(i)
        fmt.Println(i, ": ", *colName)

        // The following line demonstrates to to get the column
        // index given a column name:
        idx = csv.GetIndex(*colName)
        fmt.Println(*colName, " is at column index ", idx)
    }
