The zip file yagiu112.zip contains version 1.12 of the code. Documentation is *only* in unix man pages. However, DOS executables are posted in the version 1.12 of the code. If you cant use the man pages, please copy the version 1.09, where you will find ASCII and possibly (cant recall) postscript version of the docs. These however, are of course more out of date. I am sorry, but at the present I dont have the time to produce all the other versions of the docs that I once did. dave kirkby G8WRB e-mail davek@medphys.ucl.ac.uk
