Fortran – ISO/IEC 1539

A blast from the past!

Here is the classic “Hello, World!” program in Fortran – ISO/IEC 1539:

PROGRAM hello
  IMPLICIT NONE
  CHARACTER (LEN=12) :: greeting = 'Hello, World!'
  WRITE (*,*) greeting
END PROGRAM hello

Let me explain what’s going on:

  • PROGRAM is the keyword to define a Fortran program.
  • IMPLICIT NONE specifies that all variables must be explicitly declared.
  • CHARACTER (LEN=12) :: greeting = 'Hello, World!' declares a character variable greeting with a length of 12 characters and initializes it with the string “Hello, World!”.
  • WRITE (*,*) greeting prints the value of greeting to the console.

To compile this program, you’ll need an Fortran compiler that supports ISO/IEC 1539. Some popular options include:

  • gfortran (part of the GNU Compiler Collection)
  • ifort (Intel Fortran Compiler)
  • pgfortran (Portland Group Fortran Compiler)

Once compiled, simply run the executable to see the output: “Hello, World!”
