Compiler module fortran

How do modules work in Fortran?
A module is like a package where you can keep your functions and subroutines, in case you are writing a very big program, or your functions or subroutines can be used in more than one program.
Modules provide you a way of splitting your programs between multiple files..
How does Fortran compiling work?
Before your program can be executed, it must be compiled.
This converts the English-like text of a Fortran program into a binary form that the processor understands.
It is important that you understand what is happening here: gfortran is the name of the Fortran compiler..
How to compile a Fortran module?
If the module and the code that uses the module are in separate files, you must first compile the file that contains the module.
If they are in the same file, the module must come before the code that uses it in the file.
If you change any entity in a module, you must recompile any files that use that module..
What are Fortran .MOD files?
mod files are auto-generated by the compiler from the source files and they are compiler dependent (that is, a Fortran compiler can only use module files produced by that specific compiler).
If a. f90 contains the statement module a then compiling a. f90 will produce both a.o and the module definition file a. mod..

Why use modules in Fortran?
Modules are the preferred way create modern Fortran libraries and applications.
As a convention, one source file should always contain only one module, while the module name should match the filepath to allow easy navigation in larger projects..

Modules provide you a way of splitting your programs between multiple files.
Fortran is a compiled language, or more specifically it is compiled ahead-of-time.
In other words, you must perform a special step called compilation of your written code before you are able to run it on a computer.
mod files are auto-generated by the compiler from the source files and they are compiler dependent (that is, a Fortran compiler can only use module files produced by that specific compiler).
If a. f90 contains the statement module a then compiling a. f90 will produce both a.o and the module definition file a. mod.

1995 edition of the Fortran programming language standard

This is an overview of Fortran 95 language features.
Included are the additional features of TR-15581:Enhanced Data Type Facilities, which have been universally implemented.
Old features that have been superseded by new ones are not described – few of those historic features are used in modern programs although most have been retained in the language to maintain backward compatibility.
The current standard is Fortran 2018; many of its new features are still being implemented in compilers.
The additional features of Fortran 2003, Fortran 2008 and Fortran 2018 are described by Metcalf, Reid and Cohen.
