Hello,

I am writing a program and would like to know how to make the program exit when the user presses the 'ESC' button on the keyboard

Thanks! Smile

If you set up a simple program to get a key from the user, you can find the ordinate value of any key they input. Having said this, you can easily find the ordinate value of the escape key. Once this is found, you can simply check the ordinate value of the key the user presses to see if it matches the one ordinate value of the escape key.

Use the ord function.

code:
var Sample : string(1)
Sample := "b"

ord("A") = 65
ord(Sample) = 98

The escape key's ASCII value is 27. That means you represent the escape key with chr (27).

Turing:
loop
    exit when getchar = chr (27)
end loop

the problem with using exit is that it exits the loop, I want the entire program to end Sad

If it wasn't so frowned upon, I WOULD say

code:

quit when getchar=chr(27)

Make a variable called exitgame and have it so that when you want to have the game exit, it becomes true. So each loop would have an if statement before it. Like this:

Turing:
var exitgame : boolean := false

if exitgame=false then
     loop
          blah blah
          if getchar=chr(27) then
          exitgame := true
          exit
     end loop
end if

if exitgame=false then
     loop
          blah blah
          if getchar=chr(27) then
          exitgame := true
          exit
     end loop
end if


Something like that.
