Echo batch file arrays using a variable for the index?

Question

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 t

Answer 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 %%v
setlocal enableDelayedExpansion
echo !myvar[%x%]!
endlocal

I would recommend you to use

setlocal enableDelayedExpansion
echo !myvar[%x%]!
endlocal

as it is a best performing way
