Who is the world's oldest working programmer?

On Behalf Of Mouse are more which support FORTRAN well and C badly. I just think they are rare compared to the swamp of machines with C but no FORTRAN. Whilst I agree with the sentiment, consider the following proposition:- 1. The vast majority of "Machines with 'C'" are "machines with GNU "C"' 2. If the GNU compiler package is fully implemented GNU Fortran should run on any machine with GNU "C" (well C++) Given the above it would appear to me that machines with "C" but no Fortran (available/possible) are also pretty rare beasts, and largely exist because of lack of demand... ... actually it appears that the PDP-8 doesn't have a proper "C" compiler but it does have Fortran. I wonder how many PDP-8's still exist.... .. and finally if we change the definition to "machines with a self hosted "C" compiler" as "opposed to "C" via a cross compiler" then I think the numbers would equalize.... Having said all that I am still not going to write any new code in Fortran, well except that I want a HangMan program for my IBM1130 FPGA emulation and Pen Plotter for demo purposes and I don't have "C" for the 1130 so it is going to be in FORTRAN... Dave G4UGM of support aside, FORTRAN is usually a better language than C for heavy numerical code, which is what "scientific programming" designed as an OS implementation language. That neither is all that great at the other's task is hardly a surprise.)
