Intel fortran

Fortran compiler.

How to start
Example 1:

!file 1, test1.f90:
      program test
      integer a, b, sum
      a=10
      b=53
      sum= a*b
      write(*,*) sum
      end

To compile into the executable file prog:

ifort -o prog test1.f90

Example 2:

!file 1, test.f90:
      program test
      integer a, b, sum
      a=10
      b=53
      sum= mult( a, b )
      write(*,*) sum
      end

!file 2, mult.f90:
      function mult( a, b )
      integer a, b
      mult= a*b
      end

To compile both together into the executable file prog:

ifort -o prog test.f90 mult.f90

First compile mult.f90 into an object file, and then compile test.f90 and link mult.o into the executable prog:

ifort -c -o mult.o mult.f90
ifort -o prog test.f90 mult.o
