Finally determined the problem. For some reason the location of the files was not in the Library. I tracked down their locations, put them in the Library and things now compile. Thanks for your help in tracking this down.
Had to get a new PC. Put Delphi 2009 on it (can't afford Embarcadero's ridiculous price) and when I try to compile an old project it says the dpr file is missing. It is not missing. The file is there. Any idea what is missing?
