Exit Statement

[Turing_Noob]

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.

i've already tried

exit when hasch(81)

but it says error, can you give me the could that would do that

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:

code:

If there was a key hit then     exit when the key is 'q' or 'Q' end if

Note that is pesdocode.


Edit: Input.KeyDown will also work. See the example for Input.KeyDown in the turing documentation.

if hasch "q" then
exit
end if

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 )

Too right. That was my fault for leaving that out.
