Abstract : An effective technique, employing the Principle of Least Squares, which leads from the values of the crystal structure invariants to the values of individual phases, has recently been obtained. In the present report the details of the computer program which implements this technique are described. An auxiliary program to identify the required structure invariants has also been written and is contained herein. (Author)
