I was a great fan of Turbo Pascal during the early days of personal computers. Even today, although I use Fortran for scientific and numerical procedures, I still turn to Pascal (now Delphi) now and then. The new development environment called FireMonkey enables one to write programs for Windows and Mac OS as well as IOS with one code base.
Here are some links from other enthusiasts:
I have a page of links to pages from Embarcadero, the developers of the Delphi programming environment.
