To facilitate settlement and hence trading of securities, each security has a unique identifying code. There are several types of identifying code, the one that is used internationally being the ISIN, or International Securities Identifying Number. Every security in almost every country has an ISIN (possibly excepting Colombia, whose government bonds-uniquely-appear to lack an ISIN). The structure of an ISIN is defined in ISO 6166, and the algorithm is described by Wikipedia. Defined below is an Excel VBA function LastDigitISIN(ElevenChars As String) As String that returns the last digit of an ISIN given the first eleven. UK securities also have a SEDOL number, also defined in Wikipedia. The function LastDigitSEDOL(SixChars As String) As String returns the last digit given the first ?6 characters. If the input is shorter than six characters it is left-padded with zeroes. ISINs of UK securities are typically made by prefixing the SEDOL with “GB00” (and perhaps with “IE00” for Irish se

My research into numerical simulations of many-body (N-body) gravitational interactions spans over 40 years, and is reported in several publications and my book. I have developed a set of FORTRAN codes which describe the dynamics very closely, and these are regarded by many as the de facto standard. I have explained below how you can download these codes for execution on your local computer system.
