How do I edit default programs?

I want to see the coding behind the default computer programs, like worm and adventure and stuff, but I can't look at it by using just the normal edit command. Is there any way that I can do it in-game without going into the game file?

"edit" can certainly open them, so long as you enter the correct commands.
Eg, if you wanted to edit the "worm" script you might do:

edit /rom/programs/fun/worm

… or:

cd rom
cd programs
cd fun
edit worm

You can't save changes into the rom directory, though. If you want to actually make changes you might make a copy to the root of your computer's drive and work on that instead:

cp /rom/programs/fun/worm worm
edit worm

You can see the rom directory structure here (and also view the source files through your browser, if you wish).

I'm not sure what you're talking about, you should be able to read them thru the edit program.
Try: edit /rom/programs/fun/worm

Oh, ok. Thank you for your quick reply :)/> I was not aware that they weren't just under the rom directory. That makes sense now.
I just wanted to see the code so I could maybe learn a bit more about Lua, so I just wanted to read it. Thanks a lot :)/>
