Here's a classic one:
Brainteaser #11
Write a "quine", that is, a program that will display its own code, including the PROGRAM:NAME at the top of the program. For " and → you may use a substitute symbol, but in all other ways, the output must look exactly as the program does while editing it.
I have an (84 bytes + # of characters in name) solution, but I don't feel convinced that this is the smallest you can get.
P.S. when you get it, be careful not to accidentally press CLEAR and delete the code when you think you're clearing the output!

I have one that's 47 bytes in the mem menu: (tell me if this is cheating)

[s]I can find a way to do it while imitating the store symbol. Tell me if this is legal.[/s]
Nevermind, that ruins things.

Assuming Ans is "PRGM:NAME :Ans"
Code:
PRGM:NAME
:Ans

that doesn't display the second line. only output has linewrap.
and I think you need to store something in ans in the program, instead of asuming what it is. |

| DarkerLine, did your result take up more than one screen? |

I managed to fit it on one screen, barely (thus avoiding the touchy issue of what to do if you have more than one screen).
I also discovered an optimization of sorts. If you call the program prgmGDB1GDB1 then you can refer to that name, inside the program, with two GDB1 tokens rather than by typing out the name - this saves 4 bytes every time you do it.

Haha, you need to think outside the box for this problem. It's a nice one  |

Yeesh....this is the hardest teaser yet. Urm....I'm on vacation as of now, but I have my calc with me (duh!) so maybe'll I'll come up with something tonight while we're watching the Food Network.
Neekstar, you make it sound like you have a solution.  |

I already made an assembly version of that. I call it a thing that lets you scroll through your memory.

Outside the box, but still, we would just look in program B

[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
prgmA
Text(-1,0,0,"prgmA",Text(-1,0,0,[prgmA]
I substituted [ for "
Does it work? |

| Not quite. Aside from the fact you have a missing quote before the Text(, it also doesn't exactly reproduce its code. For example, the program contains two Text( commands while its output only contains one. |

@Fallen Ghost Your program won't work unless program b is [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Output(1,1,"prgmA
Output(2,1,"prgmB |

Is there supposed to be another quote after the comma before the second Text? Tecnically, it doesn't display everything because only one Text shows up on the screen, but there are 2 in your program. Whoever it was that came up with the challenge made it sound like it had to be EXACTLY the same.
Oops, darkerline beat me too it. That will teach me to do laundry while typing my post

This is very very hard. I don't see a way.
