You can download a text calendar I wrote from my web site
http://thunder.prohosting.com/~oasys/frameex1.htm

on the files page.

I also used the following in an accounting program as a "reminder" file

put "boxes" accross the screen with sunday - saturday as heasings.
Use Sunday.fil, monday.fil etc to store actual info.
print the first few words of each file (is appicable) in the appropriate box.
if they put the cursor in that box and press enter, they can edit that file.
