where was the first high-level language operating system created
History of programming languages In 1954, language FORTRAN was invented at IBM by John Backus; it was the first widely used high level general purpose programming language to have a functional implementation, as opposed to just a design on paper.[7][8] It is still a popular language for high-performance computing[9] and is used for programs that benchmark and rank the world's fastest supercomputers.[10]
