I'm defining lists in a batch script and then like to print a specific element in each one of them, but getting an 'ECHO is off' output (is if it's empty).

I tried cycling trough the lists with a FOR loop and that worked fine.

This is the code for i'm trying to run

@echo off

rem --------start of Define list--------
set clist= A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
set ilist= X Y Z A B C D E F G H I J K L M N O P Q R S T U V W 
set testl= 1 2 3 4
rem --------end of Define list--------

echo %clist[1]%
echo %ilist[1]%
echo %testl[1]%

Expected output:


Actual output:

ECHO is off
ECHO is off
ECHO is off

Here's an example using the method described here, for creating your array like variables:

@Echo Off & SetLocal EnableDelayedExpansion

Rem ------- Start of define list -------
Set "clist=A B C D E F G H I J K L M N O P Q R S T U V W X Y Z"
Set "ilist=X Y Z A B C D E F G H I J K L M N O P Q R S T U V W" 
Set "testl=1 2 3 4"
Rem -------- End of define list --------

Rem ------- Start of array lists -------
Set "i=0"
Set "clist[!i!]=%clist: =" & Set /A i+=1 & Set "clist[!i!]=%"
Set "i=0"
Set "ilist[!i!]=%ilist: =" & Set /A i+=1 & Set "ilist[!i!]=%"
Set "i=0"
Set "testl[!i!]=%testl: ="& Set /A i+=1 & Set "testl[!i!]=%"
Set "i="
Rem -------- End of array lists --------

Rem ----- Start your commands here -----
Echo %clist[1]%
Echo %ilist[1]%
Echo %testl[1]%
Rem ------ End your commands here ------

If it was really your intention mimic an array, then it would be something similar to this.

@echo off
setlocal EnableDelayedExpansion

set "clist=A B C D E F G H I J K L M N O P Q R S T U V W X Y Z"
set /a cnt=0
for %%a in (%clist%) do (
   set "clist[!cnt!]=%%a"
   set /a cnt+=1
for /l %%i in (0,1,!cnt!) do echo( clist[%%i]=!clist[%%i]!

You can also separately echo the variables.

echo %clist[1]%`

  • A space separated list does not an array make. When cmd.exe people talk about an "array," they usually mean creating multiple variables. var[0], var[1], var[2], etc.
  • There is no any concept of lists or arrays in batch scripting, only normal environment variables (like VAR); but those are sometimes named like array-elements (like VAR[0], VAR[1], etc.), which I call usually pseudo-arrays.
