Program Development

The program development process consists of a number of stages some of which may have to be repeated several times until the end product is correct:
1.
Designing the program and writing the source-code text.
2.
Keying in the text to produce a set of Fortran source files.
3.
Compiling the source code to produce a set of object modules.
4.
Linking the object modules and any object libraries into a complete executable image.
5.
Running the executable program on some test data and checking the results.

The main parts of the process are shown in the diagram below.
