Abstract

Programs written in languages supporting call-by-reference continue to be of interest in functional programming circumstances where call-by-value is standard. In particular, if we can find a neat interface, by converting Fortran to Lisp we allow programmers to take advantage of an interactive functional symbolic system while running legacy numerical code. We show this can be done without unacceptable loss of efficiency. In building a combined symbolic-numeric environment such a conversion and combination may increase the synergy between the two approaches to scientific computing. This paper builds upon earlier reported work on f2cl.
