を、あなたはこのゲームの作業を取得するために行うには少しより多くの仕事を持っているが、私はしましたスケルトンのフレームワークを得ることができました。[無料のスタイルクリーンアップをご容赦ください]：

.data 

Welcome1: 
    .ascii "\n Hello! you are about to play the mastermind" 
    .ascii " guessing and logic game,Bulls & Cows!\n" 
    .ascii "The Computer will generate a secret number made of 4 unique" 
    .ascii " integer numbers. You have to guess the number!\n" 
    .ascii "Using the number of Bulls and Cows you get to find out what" 
    .asciiz " the secret number is!\n" 

Welcome2: 
    .ascii "\nEvery digit you enter that is both correct and in the right" 
    .ascii " location is a BULL. When you get 4 BULLS, YOU WIN!\n\n" 
    .ascii "Every digit you enter that is correct, but not in the right" 
    .asciiz " location is a COW!\n" 

confirm: 
    .ascii "\n Select \n" 
    .ascii "YES - if you are ready to guess\n" 
    .ascii "NO - to see the rules again\n" 
    .asciiz "Cancel - to exit the Game\n" 

msg_asknum: 
    .asciiz "\nEnter your game choice\n" 

    .text 

main:
