Batch Script How to Set Variabes inside another variable

问题

i want to do something like this

1.bat

var1=The bot now At %PlaceName%

2.bat

SET PlaceName=Hotan
Echo %var1%

it should be like:

The bot now At Hotan

but it is shown like:

The bot now At %PlaceName%

回答1:

1.bat

@echo off
setlocal

set "var1=The bot now At !PlaceName!"
call 2.bat

2.bat

@echo off
setlocal EnableDelayedExpansion

SET PlaceName=Hotan
Echo %var1%

Another way:

1.bat

@echo off
setlocal

set "var1=The bot now At %%PlaceName%%"
call 2.bat

2.bat

@echo off
setlocal

SET PlaceName=Hotan
call Echo %var1%
