问题 Good afternoon, I would like to add the simpliest tag into a file, using a CMD batchfile, but it seems that the double quotes are spoiling the party: From other StackOverflow posts I am aware of the double quote state machine and the usage of ^" (^ as an escape character). Still I can't make it work: Hereby my attempts (with their results): C:\>echo <tag variable="value"> // very naïve The syntax of the command is incorrect. C:\>echo "<tag variable="value">" // let's use quotes for delimiting

问题 If I have a batch file and I am setting arrays with an index that is a variable @echo off SET x=1 SET myVar[%x%]=happy How do I echo that to get "happy" ? I've tried ECHO %myVar[%x%]% ECHO %%myVar[%x%]%% ECHO myVar[%x%] But none of them work. It works fine if I use the actual number for the index ECHO %myVar[1]% But not if the index number is also a variable 回答1: SET x=1 SET myVar[%x%]=happy call echo %%myvar[%x%]%% set myvar[%x%] for /f "tokens=2* delims==" %%v in ('set myvar[%x%]') do @echo

问题 In windows batch could you set a variable within a variable? Explained: So the %num% is within the variable. set num=5 set cnum=test set h1=%c%num%% Is it possible to make the percents work like parenthesis? The output should be h1=test Any help would be appreciated. 回答1: Your example in your question is a mess, but I think I understand what you are looking for: @echo off setlocal set C1=apple set C2=orange set C3=banana set num=2 :: Inefficient way without delayed expansion :: This will be

问题 I have following code: @echo off SET ITER=0 for %%i in (%*) do ( SET ITER+=1 ECHO %ITER% ) The output is (for three arguments): 0 0 0 Expected output: 1 2 3 Why can't I access the updated variable in the for loop? 回答1: Expansion of variables with percents is done before a statement/block is executed. So in your case the complete block is expanded before the echo %ITER% is executed, to constant echo 0 . The variable ITER itself is updated in the loop properly. To avoid this, you could use the
