The article "The Fortran I compiler", Padua, D., Computing in Science
& Engineering [see also IEEE Computational Science and Engineering]
,Volume: 2 , Issue: 1 , Jan.-Feb. 2000, Pages:70 - 75 has some
discussion of parsing in the original Fortan 1 compiler, and is
generally an interesting article on early compiler technology.
