Fortran is the oldest programming language still in widespread use. The language has
FORTRAN 77, being quite old, lacks almost everything one expects from a modern programming language. It uses a fixed-length line and column oriented line format which was motivated by punch cards. Due to its age, and since FORTRAN compilers generally gave very good performance for numerical code, a lot of code, especially scientific code, was written in FORTRAN. Also, for quite a while there was no free Fortran 90 compiler, which also caused a lot of FORTRAN 77 code to be written even quite some time after Fortran 90 was standardized. Because of the large body of code written in FORTRAN 77 it remains relevant today. Indeed, every modern Fortran compiler still accepts FORTRAN 77 code.
