Changing position of text cursor.

[Aziz]

How would I go about changing the position of the text cursor (like a locate command in turing)

You don't. You print to the standard output, rather than a special window as in Turing. It's just linear text.

Why do you think you need this capability anyway? (What are you trying to accomplish?)

[Aziz]

Just input, but idiot-proof. So if they type in a string when the program needs an integer I go back to original line. But I get what you're saying

I know very limited Java, but wouldn't you do that with a simple loop?

pseudocode:

loop get input if the input is an integer then continue the program if the input is anything else then go back continue the loop

[wtd]

Yes, but I believe Aziz was trying to hide the original input.

Bad practice in a text UI environment. The ser knows they input that, so hiding it serves no purpose.

Ok, I agree, he still might want it for aesthetic (sp?) purposes, I don't know. Still, to do that wouldn't you just add a "clear the screen" to the loop?

There's no portable way to do that. And not because no one has ever thought of doing it before.
