toms436, a FORTRAN77 code which implements ACM toms algorithm 436, which carries out a product type trapezoidal integration to estimate the integral from A to B of F(X) * G(X).
While the text of many ACM toms algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html, most of the early algorithms are not available. This is one of them. I typed it in.

toms436 is available in a FORTRAN77 version.
