What is it you are trying to achieve? create a program which starts with a blank output window. check whether a key has been pressed, and if the D key (or d key) has been pressed, draw a graphic of some kind (oval, square, maple leaf) in a random position on the screen. if the D (or d) key is pressed again, clear the screeen and draw the image again in another random position. if X or x is pressed, exit the program. What is the problem you are having? i cannot get the program to exit when you press 'x' or 'X' Describe what you have tried to solve this problem i tried placing an exit statement, but i dont think its in the right spot. Post any relevant code (You may choose to attach the file instead of posting the code if it is too long) var input : string (1) := ' ' var x, y : int x := 50 y := 50 loop if hasch then getch (input) put "The key you entered was ", input delay (500) if input = 'd' or input = 'D' then drawfillmapleleaf (x, y, 200, 200, 31) randint (x, 1, maxx) randint (y, 1, maxy) drawfillmapleleaf (x, y, 200, 200, 12) exit when input = 'x' or input = 'X' end if end if end loop put "Goodbye"
Please specify what version of Turing you are using 4.11 |

Simple... your exit when statement is in the wrong location. |

does it go after the loop? |

look at where it's placed. Try running this: var ch : string (1) loop getch (ch) if ch = "f" then if ch = "q" then put "hi" end if end if end loop Will this program ever put "hi"? This is essentially what your program is doing right now. |

Well, if you put the exit when statement just before the end loop it will work, basically, it is not reaching your statement. |
