The archive file anduct.zip contains the files:

lew14000.txt the program description from COSMIC
readme.txt general description
original.src the original copy of the source code (from COSMIC)
an.f90 the complete source code in modern Fortran

This program is a "work in progress" and is not ready for general release. I have included it on the disc so those who have a special interest may see the original code plus my modifications to date.
