This sounds interesting and curious what you come up with.

Hey, I wrote an OS in TI-BASIC one time with a start menu, games, notepad, paint, and some other stuff.  So its certainly possible.  But realistically, I don't think you'll be able to do program launching from a program since it would need to copy it over it's own code, destroying the shell.  It pretty much has to be an application to do that.  I like the idea though, there's still probably a lot you can do, certainly much more than BASIC.

Did you ever release the OS program you made?

I'm pretty sure it was Red Version that ran fine, I haven't checked that document in a long time though.

Well I mean I could its just that either way the person will have to type the program in manually because I don't plan to post a program file for that is all. They could just add it themselves. The reasons I put the variables there isn't to be used in the program but to be substituted for those values. I don't know if that makes sense but ya.

Well in theory if the a program is in basic you can't jack your calculator up, but you can do fake programs that just annoy the user. But there are also programs that can do RAM clears or even do worse like erase the OS or certificate (in that case you're basically screwed unless some like BrandonW can help ya out). The programs that do that are Assembly programs.

Well it's still pretty cool

By the way, what is the difference between isometric and non-isometric pixel art?

Very cool. The only FarmVille pixel art I see is the one with the splash screen when you run it. Nice to see someone actually do it.

So I recently made a copy and pasting program, some of you may know that already, but Builderboy gave me a idea about a different way of doing it that just has more restrictions. So since it is a pretty simple routine I came up with I thought I would share it here for anyone interested.

Note:
Really the only drawback with this method is that if you need to move the image somewhere where it would overlap the original position it will not work properly (sometimes it will, depending on the image; I may give an example of both).

Ok, the code for it:

For(A,Y',Y") //Y' is the starting Y coordinate and Y" is the ending.
For(B,X',X") //Same deal. X' is starting X coordinate and X" is the ending coordinate.
If pxl-Test(A,B
pxl-On(A±C,B±D //C and D are used to shift the image into the spot you want. Say the image is at (32,36) and
pxl-Off(A,B    //you want it at (0,0). C would equal -32 and D would be -36.
End
End
I hope this makes sense and is helpful to someone. I'll go over it later and try to show an example of when a pic can overlap coordinates, if I can manage it. Enjoy.

Edit:
I made it so that restriction is no longer applicable.
