    No such thing as
    Code:
    Input = Reverse
    The function should just return a FLAG. You are going about it the wrong way. Don't try to reverse the original string. Create a copy, and reverse that.

    Re: isPalendrome function

    Here's a function to reverse text if you need one:

    # Private Function Reverse(ByVal Input As String)
    Dim CharNbr As Int16, ReverseString As String
    Dim StringArray() As Char = Input.ToCharArray

    For CharNbr = UBound(StringArray) To 0 Step -1
    ReverseString &= StringArray(CharNbr)
    Next

    Return ReverseString
    End Function
    #

    That is for numbers, not text

    Not sure I understand you. The original post wanted to reverse a string and that's what the function does.

    My mistake. Sorry.

    You probably get an A+ on the quiz
