Hi Jim The algorthhm.DOC file was in a DOS-Windows Microsoft Word format. I also have a Mac, and was able to open it in ClarisWorks. If you drop the file on the ClarisWorks icon, it may not open, but if you start ClarisWorks and use the Open command, then it should. I am using version 4 of ClarisWorks, and you need to have the proper translation file in ClarisWorks to translate the file proplerly. Translated, the file is 145 K in ClarisWorks. I could send you a copy if you like, but would put it in a self extracting stuffit archive which should cut the size about in half. Let me know if you wish me to do this, and what version of ClarisWorks you are using. Brian Symonds <[log in to unmask]>
