* 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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Csv')
loCsv = CreateObject('Chilkat.Csv')

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

* Load the CSV records from the file:

lnSuccess = loCsv.LoadFile("sample.csv")
IF (lnSuccess <> 1) THEN
    ? loCsv.LastErrorText
    RELEASE loCsv
    CANCEL
ENDIF

* Display the column names:

FOR i = 0 TO loCsv.NumColumns - 1
    lcColName = loCsv.GetColumnName(i)
    ? STR(i) + ": " + lcColName

    * The following line demonstrates to to get the column
    * index given a column name:
    lnIdx = loCsv.GetIndex(lcColName)
    ? lcColName + " is at column index " + STR(lnIdx)
