I am trying to compile the sample code provided in example 1 of [this link][1] using GNU Fortran. I have placed the source code in a .f95 file called "Test" and tried to compile it in `cmd` using

`gfortran test.95`

This throws quite a few errors as shown below:

Why is this happening? How can I fix it?
