Introduction to Fortran

Machine code (numeric notation in octal);

  • mnemonic code assemblers;
  • 1954: project creation of the first language symbolic FORTRAN by John Backus from IBM (Mathematical FORmula

TRANslating System):

  • Efficiency of generated code (performance);
  • Quasi natural language for scientists (productivity, maintenance, readability).
  • 1957: Delivery of the first compilers;
  • 1958: Fortran II (IBM) ⇒ independently computable sub programs.
  • Generalization to other manufacturers but:
  • Divergence of extensions ⇒Normalization requirement;
  • ASA American Standards Association (ANSI).

Committee for the development of a FORTRAN standard. 1966: Fortran IV (Fortran 66);

  • Evolution by divergent extensions. . .
  • 1977: Fortran V (Fortran 77).

almost compatible:
no iteration of the null loops (OD I = 1.0)

  • Main news:
  • type character;
  • IF-THEN-ELSE;
  • Direct access I / O and OPEN.

Introduction History

  • Work of the X3J3 / ANSI and WG5 / ISO committees to modernize Fortran 77:
  • Standardization: inclusion of extensions;
  • Development: new concepts already exploited by newer languages APL,

Algol, PASCAL, Ada; . . .

  • Performances in scientific computing;
  • Fully compatible with Fortran 77.
  • 1991/1992: Fortran 90 standard (ISO and ANSI);
  • 1994: Fortran 90 Cray and IBM first compilers;
  • 1997: Fortran 95 standard (ISO and ANSI);
  • 1999: First compilers Fortran 95 on Cray T3E then IBM RS / 6000;
  • September 2004: Fortran Standard 2003 (ISO and ANSI);
  • October 2010: Fortran Standard 2008 (ISO and ANSI).
