I didn't mean that you could output to a file -- I meant that, knowing the name of the file the program is saved to (which is possible using facilities available in many modern languages, not sure about Fortran), you can ingest that file and print out its contents (to STDOUT for example). It feels like cheating, but it's also probably the easiest way to get a true quine which'll always work even if you modify parts o…

Many years ago, I attempted to cheat this way when writing a JScript quine- but it didn't work because the Windows Scripting Host keeps the source file open while interpreting it, which meant the script couldn't open its own source file because the file was already open in another program! A proper quine, though, doesn't require input.

A multiquine does require you to give input in order to determine what language to output. Although it will output the current file if no input is giving. More info @ https://en.wikipedia.org/wiki/Quine_(computing)#Multiquines
