hasch and getch program

-----------------------------------

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"

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.
