この数学チャレンジプログラムにタイマースクリプトを追加するには？

Question

これは私のスクリプト/プログラムです。間違ったセクション：

@echo off 
cls 
color 0a 
:startup 
REM Determinant to Sign (+-*/) 
set /a deto1=%random% %%4 +1 
set /a deto2=%random% %%4 +1 
set /a deto3=%random% %%4 +1 
set /a deto4=%random% %%4 +1 
REM Set Sign from det 
if %deto1%==1 set o1=+ 
if %deto1%==2 set o1=- 
if %deto1%==3 set o1=* 
if %deto1%==4 set o1=/ 
if %deto2%==1 set o2=+ 
if %deto2%==2 set o2=- 
if %deto2%==3 set o2=* 
if %deto2%==4 set o2=/

REM Randomize digits from 1-9 
set /a d1=%random% %%9 +1 
set /a d2=%random% %%9 +1 
set /a d3=%random% %%9 +1

REM Operation for final answer stored inside memory 
set /a answer=%d1%%o1%%d2%%o2%%d3%%o3%%d4%

cls

to whole numbers. (60 seconds)

echo. 
set /p userans=Answer(Only sign in order from Left to Right): 
REM Comparasion of user answer to correct answer in memory 
if %userans%==%o1%%o2%%o3% goto :correct 
if not %userans%==%o1%%o2%%o3% goto :wrong 
:wrong 
cls 
title That's wrong! :( 
echo. 
echo That's wrong unfortunately because the answer is 
%d1%%o1%%d2%%o2%%d3%%o3%%d4%=%answer%. Try another one! 
echo. 
pause 
goto :startup 
:correct 
cls 
title That's correct! :) 
echo. 
echo That's correct as from %d1%%o1%%d2%%o2%%d3%%o3%%d4%=%answer%! Try 
another problem. 
echo.

goto :startup 

だから、どのように我々は時間にプレーヤーが にリダイレクトされるまで60秒間意志を持続し、この数学の挑戦をタイマースクリプトを追加します。私はタイムアウト/ t 60/NOBREAKのような多くの方法を試しましたが、ユーザーの入力（セット/ p）の前にスクリプト化されている場合、プレイヤーは問題を解決するために提示されませんが、入力はプレーヤーにもタイムアウトされません。 & &を使用すると、入力とコマンドの両方を一度に実行すると、表示されていない空白の画面も同じ画面も返されるため、正しく動作しないようです。他のストップウォッチスクリプトの実装も同じ問題に直面しています。

私は余裕がありましたので、この問題の解決策を完了しました。動作しているようです
