// 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:

// Load the CSV records from the file:

    Write-Debug loo_Csv.LastErrorText

// Change "blue" to "magenta"

// Write the updated CSV to a string and display:

Write-Debug ls_CsvDoc

// Save the CSV to a file:
