// 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

end if

// Prior to loading the CSV file, indicate that the 1st row
// should be treated as column names:
loo_Csv.HasColumnNames = 1

// Load the CSV records from the file:

li_Success = loo_Csv.LoadFile("sample.csv")
if li_Success <> 1 then
    Write-Debug loo_Csv.LastErrorText
    destroy loo_Csv
    return
end if

// Display the column names:

    ls_ColName = loo_Csv.GetColumnName(i)
    Write-Debug string(i) + ": " + ls_ColName

    // The following line demonstrates to to get the column
    // index given a column name:

    Write-Debug ls_ColName + " is at column index " + string(li_Idx)
