how do you make an exit statement so that when q or Q is press then the loop will exit? |

Well the function for checking if a key is pressed is hasch. And you can exit a loop with exit. |

Sorry, i thought you wanted it to exit when any char was hit. What you will have to do is use hasch to check if a key was hit and then check if it was equal to 'q' or 'Q' with getch or getchar. It would be somthing like this:
Note that is pesdocode. Edit: Input.KeyDown will also work. See the example for Input.KeyDown in the turing documentation. |

Dan, it's great that you're trying to help, but it helps no one when your code doesn't work. What Dan said above is probably the way to go. |

You understand if you are getting input that it is hsch but you can't say if hasch "q" you need to declare a string variable and get that variable then compare the vlue of that variable with "q" or "Q" You could look into getch aswell (I pronounce it getch not get ch ) |
