IBM invented PL/1. IBM (or at least IBM Canada) wrote their excellent Fortran compilers in a subset of PL/1 called PLIX, that is PL.9. I guess a full language was too hard even for the inventors of the language. At committee meetings I would pester the IBM delegate "When are you going to make your compiler available for Linux on Intel?" His answer was always NEVER!
