Convert about a hundred lines of perl into a VBA function (e.g. usable as an Excel macro or an MSAccess module).
Original code takes a string as a parameter, does complex bit operations to compute a type of checksum, and then loads a web page using that value, parses out one number and prints it. See attachment.
Finished code should be a function that takes a string, does the checksum use the XMLHTTP object to load the web page. e.g. Dim http As New XMLHTTP, [url removed, login to view] "GET", url, http.send. And then returns the same number printed by the original code.
