Oh, it would be an excellent project. In that I was serious.
But I seriously (so I was serious in another respect too :) ) don't think he could pull that off so the suggestion of the project was sarcastic ;)
I once made my own programming language. You didn't have to compile it, it was just in a .TXT file. The only command I ever implemented was openNotepadWindow(). So you'd have a program like this:
And when you double clicked it and ran the program it would open a Notepad window. Cool, huh?
sorry but i hate to bust your bubble, but that's not a programming language. if you don't compile then it's just pure scripting.
Java, C++ are actual programming languages...
but the intersting thing here is that Java was made from C++ so how's that for your own programming language
