I want my program to continue when the user presses the enter key so

Turing:

var enter : string (1) := chr (13)

loop
    Font.Draw ("Press ENTER to restart", 180, 80, defFontID, black)
    if hasch then
        getch (enter)
        exit
    else
    end if
end loop


but it continues anyway no matter what key I press. What am I doing wrong?

You need to getch a key then exit your loop when that key is enter.

Very basic and easy to do.
Turing:
var Keys : array char of boolean;
loop
Input.KeyDown (chars);
exit when chars (KEY_ENTER)
end loop/*exits loop when exit statment is true*/
put "Exited" /*to prove this works*/

If you break your program down line by line you are creating the variable enter and assigning it to chr(13)

Isn't enter 10?

Then you are in a loop displaying instructions then

Turing:
if hasch then
        getch (enter)
        exit
    else
    end if


Means if a key is pressed (hasch) then get a value for enter then exit the loop.

So it doesn't matter what key you enter it will exit.

try using an exit when statement.
