In need of help for my Turing Game!!

[programmerNeedsHelp2.0]

I am currently making a game which consists of four levels. I want to program the game so that if the user loses any level (in which a "game over screen" is displayed), it tells the user to press a certain key to go back to the main menu of the game, in which the user can play the game again if he/she wants to. (so it has to repeat all code written prior to the displaying of "game over" screen, within the same file) But I can't figure this out! Is there anything similar to a goto statement as seen in c, python, and other languages? Here is the code:

This is extremely difficult to do if you're using processes at all in your code. You should be using procedures instead. Processes will give you all kinds of unpredictable bugs that are impossible to solve.

The easiest way to do what you're asking is to wrap the entire game in a loop. The first thing that loop does is set all variables to the starting condition. The next thing it does is ruin your game loop (again, inside the giant everything loop). When the game is won/lost, the game loop exits, which returns control to the giant loop, which restarts and automatically resets all variables. It should look like this:

%declare all variables
Loop
%assign all variables
Loop %main game loop
%game code goes here
Exit when game is lost or won
End loop
End loop
