How to write a self-printing program

It's most convenient to do this in BASIC (the dialect I remember is MS-BASIC), because it has a command (function?) for listing a program's code:

  10 LIST

First saw this 30 years ago - did it in Basic at the time. Two solutions - the pedantic one, where you include the source in constant declarations, then the code that prints the constants twice, once with declarations around them.

The other - an empty program. Run it - nothing. List it - nothing.

If the author sees this - "quine" should be capitalized, as it's named after a real person (a philosopher - quite a good one). Like "Volts", for example.

[update] Hmm, although both Wikipedia and GEB use lower case. But in GEB it's lower case because it's a verb (quining). Not sure it's used as a noun - (there are index entries for "Quine" and "quining").

[And edited to add caps as i guess otherwise someone will complain]

Maybe I'm missing something, but is the following valid?

    #!/usr/bin/python2
    print open(__file__).read()
    # do other stuff as well

That is, why not just print the source file, rather than store the code within itself?

Wikipedia has a really good article on quines (self-printing programs): http://en.wikipedia.org/wiki/Quine_%28computing%29

This article comes to mind: http://orkinos.cmpe.boun.edu.tr/~kosar/ken/index.html

I did this in perl and ran it from bash.

print(system("cat perlQuine.pl"));

Is this cheating?

What about `function _(){console.log(_+'()');'and other stuff';}()`?

What about a program that reads it's source from it's debug info?
