Fortran 模块语法
示例
模块是类型声明，数据声明和过程的集合。基本语法为：
module module_name
use other_module_being_used
! The use of implicit none here will set it for the scope of the module.
! Therefore, it is not required (although considered good practice) to repeat
! it in the contained subprograms.
implicit none
! Parameters declaration
real, parameter, public :: pi = 3.14159
! The keyword private limits access to e parameter only for this module
real, parameter, private :: e = 2.71828
! Type declaration
type my_type
integer :: my_int_var
end type
! Variable declaration
integer :: my_integer_variable
! Subroutines and functions belong to the contains section
contains
subroutine my_subroutine
!module variables are accessible
print *, my_integer_variable
end subroutine
real function my_func(x)
real, intent(in) :: x
my_func = x * x
end function my_func
end module
