// This example program loads a file (sample.csv)

// 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:

    Write-Debug loo_Csv.LastErrorText
