Fortran (/ ˈ f ɔːr t r æ n /; formerly FORTRAN) is a third generation, compiled, imperative programming language that is especially suited to numeric computation and scientific computing. Fortran was originally developed by IBM. [3] It first compiled correctly in 1958. [4]
The last modification date stamp (and with DELWATCH 2.0+ also the file deletion date stamp, and since DOS 7.0+ optionally also the last access date stamp and creation date stamp), are stored in the directory entry with the year represented as an unsigned seven bit number (0–127), relative to 1980, and thereby unable to indicate any dates in ...

A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...

The first high-level language to have an associated compiler was created by Corrado Böhm in 1951, for his PhD thesis. [3] The first commercially available language was FORTRAN (FORmula TRANslation), developed in 1956 (first manual appeared in 1956, but first developed in 1954) by a team led by John Backus at IBM .
This second part of the compiler can also be created by a compiler-compiler using a formal rules-of-precedence syntax-description as input. The first compiler-compiler to use that name was written by Tony Brooker in 1960 and was used to create compilers for the Atlas computer at the University of Manchester , including the Atlas Autocode compiler.
This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.
