App is free software last released some time ago, June, 2003 (see also http://freecode.com/projects/app). The attached files were uploaded without change from my prior website at members.cox.net/nelan. All of the local html links should still work. However the global links (e.g. to the ancient primenet site and also to my prior cox site) are broken. Just ignore them or refer back to this website instead.
For more information, open the attachment app.html. (Click the link and choose the Open option if your browser supports that, otherwise you will need to download and save it first then browse locally. Another and probably better option if your machine can unzip zip files is to download and save the first attachment, _attachments.app.zip, which itself contains the other related attachments - except for alpha22.zip which you need to download separately, then unzip it and browse locally starting with the unzipped app.html file. See the Organization page for further discussion.)
Note: The appdoc subpage exists because that's the way my prior website was organized. It isn't intended to be browsed, though it can be.
