If you are interested, this program and more are on a disk called "PERFORM -- The Performance Calculator". It is available cheap, $5 plus postage. Or you can mail $4 and a diskette with return envelope and postage. PC versions only, no Mac available.

For those worried this is a commercial item, don't. At $5, this is cheaper than most "free" shareware programs.

Thanks for visiting.

I have received several notes about this page. The Java scripts do run, however, there is magic in how they run. I know that I have not had the luck of getting them to run at home, but from the library and from work I have had no problems. Also, I have received notes from several who have been very successful, also. If you have a problem, check your browser. I found Microsoft Internet Explorer, a nice piece of free software from almost every net provider, does not support Java in Version 2.0 so if you have Explorer, install Netscape 3.0 or above instead.
