Source Code on the Fortran Wiki

When contributing code, please specify a license so that others know the extent to which they may use and modify your code. All code on the Fortran Wiki shall be in the public domain unless otherwise noted. Other common licenses are the BSD, MIT, and GPL licenses.

To contribute Fortran source code, add a link here to the filename, program, or module name, and create the new page by pasting the code, wrapping it in a fenced code block with a language keyword. See the HowTo and existing pages such as hello for examples.
