The first step is to create a text file named hw.f95 using a text editor. It is useful to place programs and various files into a working directory. This way the files can be easily found and not confused with other, unrelated files and data. The hw.f95 file should be created and placed in a user created working directory. For this example, a working directory named 'fortran' was created and the file is then created and edited in that location.

A file name is typically comprised of two parts; a name and an extension. In this example, the file name is hw and the extension is .f95. The usual extension for this and future programs will be .f95 which indicates that the file is a Fortran 95/2003/2008 source file.

The following examples will use the hw.f95 file name. If desired, a different file name may be used. However, the name will need to be adjusted for the compiler and execute steps in the following sections.
