I quite agree with you. People have written big, mission-critical
programs to run nuclear reactors and design planes in Fortran 66 and
77, although I hoped that they ran static analysis programs such as
FTNCHEK to verify them. Fortran 90 and later versions has modules,
whose use allows the compiler to check types in procedure calls. I
used Fortran 77 in my physics PhD program and find that I am much more
productive in Fortran 95 now, making fewer errors not caught at
compile time. The operations on arrays and array sections in Fortran
help one to write number-crunching code that is "clear as glass".
