Question

我做了這個代碼

@echo off & SETLOCAL EnableDelayedExpansion
title TXTanimation
set dir101=C:\USers\%username%\Desktop\file.bat
goto label1
echo Lets make a text animation
pause
set /p dir101=where will the .bat be saved:
:label1
echo @ECHO OFF > %dir101%
echo: >> %dir101%
:menu
echo 0=Edit important information
echo 1=Display .txt
echo 2=Play sound
echo 3=Close sound player
echo 4=Add nessicary wait between .txt
echo 5=Label point
echo 6=Edit variable
    echo 7=Goto point
echo 8=Create IF sentence
echo 9=End it
    echo Add - to the front to view it's guide!    
    Set /p choose=which one:

If '%choose%'=='0' (
SEt /p title=What is the title
:LOL101
set /p color=what color do you want type test to experiment with the colors
If '!color!'=='test' goto tester
goto model
:tester
SEt /p test=Please give hexadecimal number type exit to leave:
if '!test!'=='exit' goto LOL101
color !test!
goto tester

echo title %title% >> %dir101%
echo color %color% >> %dir101%
goto menu
)

If '%choose%'=='-0' (
echo The title is on the top of the screen. The color of the text and backround is a hexadecimal number its 

01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F,10,12,13,14,15,16,17,18,19,1A,1B,1C,1D,1E,1F,20,21,23,24,25...FB,FC,FD,FE. There really are 

values with the same character but those are not valid colors in batch.
goto menu

現在您可能看到需要是 %variablename% 的 %!var!% yeh 知道嗎？ 我需要解釋更多，以便在修復此錯誤后完成其余批次的發貨！ 在那之前，我仍然需要刪除它在開始時回答自己的問題的那部分！

這個問題涉及如何將批處理文件中的變量擴展為其他變量的名稱，然后解決這些問題。

Answer 1

您需要學習如何將代碼提煉成提出問題所需的最少代碼，然后提出特定問題。

話雖如此，我想我理解你的問題。

我相信您正在動態構建批處理腳本，並且您希望您的代碼看起來像

echo If '%someVar%'=='someString' goto someLabel

要使輸出中的百分比增加一倍，您需要做的就是將它們加倍

echo If '%%!var!%%'=='!string!' goto !poin! >> %dir101%

Answer 2

只是%% variable %%真的很簡單
