To use any of the web page calculators off-line, go to my web pages and ensure that they are fully loaded, possibly by entering some data. The page (which includes all the calculator facility) can then be "save as" from the file menu ( as a htm file) to a directory on your hard disk. If you wish, you can come out of the Internet and then go back into the browser off-line, and save all the files at your leisure. Go into "history", find the calculator page you are interested in, then file, save, to a directory that you wish as an htm file. The web page with all the calculator facility will be available from this saved file.

Using Netscape Communicator 4.5 or above
Go to the desired web page. The file can be "saved as" to any of the directories on your hard disk. Save as htm or html file.
