2020-01-25 Notes on the status of this site

This page hasn't been maintaned for quite a long time and isn't updated regularly anymore. Links to resources related to Modula-3 tend to vanish without notice now and then. The source repositories containing the PM3 and CM3 code distributions have been moved to several years ago. As the web pages containing this site haven't followed and a maintainer still has to be found, elego Software Solutions GmbH is still keeping this VM running as a landing page for Modula-3. Anybody wishing to improve this situation is welcome to contact me.
