// The SetNth method is handy for setting a part of a delimited string.
// For example:

loSb = createobject("CkStringBuilder")
loSb.Append('red,blue,"green,purple",,yellow')

lcDelimiterChar = ","
llExceptDoubleQuoted = .T.
llExceptEscaped = .T.

loSb.SetNth(2,"magenta",lcDelimiterChar,llExceptDoubleQuoted,llExceptEscaped)
// Prints "red,blue,magenta,,yellow"
? loSb.GetAsString()

loSb.SetNth(3,"orange",lcDelimiterChar,llExceptDoubleQuoted,llExceptEscaped)
// Prints "red,blue,magenta,orange,yellow"
? loSb.GetAsString()

// What happens if we start with an empty string?
loSb.Clear()

loSb.SetNth(2,"apple",lcDelimiterChar,llExceptDoubleQuoted,llExceptEscaped)
// Prints ",,apple"
? loSb.GetAsString()

loSb.SetNth(0,"orange",lcDelimiterChar,llExceptDoubleQuoted,llExceptEscaped)
// Prints "orange,,apple"
? loSb.GetAsString()

loSb.SetNth(1,"banana",lcDelimiterChar,llExceptDoubleQuoted,llExceptEscaped)
// Prints "orange,banana,apple"
? loSb.GetAsString()
