    The B6700 algol programme TVEDIM is described. Based on the observation that the source iteration technique with a nearly complete solution of the group equations is not usually optimal, a partial inversion is accomplished by means of a frontal elimination technique. Too stringent limitations on blocksize due to stability problems are avoided by using double precision artihmetic where advantageous.
