Someone already noted in http://groups.google.de/groups?hl=de&lr=&ie=UTF-8&selm=pan.2002.01.07.19.26.43.731414.3902%40houston.rr.com that there is a procedure TtoS in PM3's M3toC where SharedTtoS, FreeSharedS, FlatTtoS are in CM3's M3toC. Seems that I have to use the copying routines instead when I want to generate modules exchangeable between PM3 and CM3. :-(
