!# This example demonstrates the most basic of FORTRAN 90 syntax                  #
!# A fortran program is case insensitive.                                         #
!# The name of this fortran file has a suffix of .f90 (there are others too)      #
!# The name itself is case sensitive                                              #
!# It starts with "program declaration and ends with "end program" declaration    #
!# All texts to the right of "!" i(until the end of line) is treated as comments  #
!# Must compile into an executable before running it                              #
