REPLACE SUBSTRING FUNCTION

Hi -

Does anyone know if Brightscript has a replace function to replace s substring of text?

for example, I would like to do something like this...

string = "this is a file name.mp4"
newstring = replace(string," ","%20")

    You can find it in generalUtils.brs in the videoplayer example.

    '******************************************************
    'Replace substrings in a string. Return new string
    '******************************************************
    Function strReplace(basestr As String, oldsub As String, newsub As String) As String
        newstr = ""

        i = 1
        while i <= Len(basestr)
            x = Instr(i, basestr, oldsub)
            if x = 0 then
                newstr = newstr + Mid(basestr, i)
                exit while
            endif

            if x > i then
                newstr = newstr + Mid(basestr, i, x-i)
                i = x
            endif

            newstr = newstr + newsub
            i = i + Len(oldsub)
        end while

        return newstr
    End Function

    Also, for your specific example, you might be interested in roUrlTransfer.Escape( string ).

    String Escape(String text)
    URL encode the specified string using CURL.

    And/Or UrlEncode()...
