Introduction 4thclock.
4thclock.exe is a program which shows important days and will generate a sound, or signal at a previous defined time. It can be used as an intelligent alarm clock. 4thclock.exe can be used at 2 levels. When it is restarted, it will continue its tasks. Old settings will be restored when restarted. Just click and run, there are no questions to answer. A complex user interface is avoided by using an ini-file. You do not need to modify it when you use 4thclock.exe on an easy level.

Background for programmers
You can download the compiler, program and sources from: http://home.planet.nl/~josv.
Compile _4thclock.f ( note: the underscore ) for testing, changing or a turnkey application.
The thinking behind the hole programs was to explore what is needed when a database is used which is not in the dictionary.

System requirements
Windows 95 or better with an Html-reader for this file.
