Again -- greetings all. I'm sorry about this but I've included the wrong post script to my last post (I guess I had more windows open than I could efficiently manage). Here is the correct version - PS When I tried to attach the self extract file, Solution.EXE, Yahoo! refused on the grounds that it was a virus which it certainly is not. I tested several other .EXE files and Yahoo! was happy with those, so it is something about my file it doesn't like. As there is more than one way to skin a cat, I then converted Solution.EXE to a five letter code group file Solution.ALF which Yahoo! accepted and is attached, but when I tried to attach codegrp.exe -- so you can convert Solution.ALF to Solution.EXE -- Yahoo! again complained, in these terms "|!| Alert! There's a problem scanning codegrp.exe for a virus. Send anyway | Cancel". Can you believe that? I won't do that so I suggest that you go to http://www.fourmilab.ch/codegroup/ and download the codegrp.ZIP file. It is dead simple to use -- the instructions are given at the site and in the zip file. Sorry about that, but not my fault. So in summary, the steps are (1) obtain codegrp.zip, extract, and RUN codegrp -d solution.alf > solution.exe (2) RUN solution.exe -s<password supplied next monday>.
