How to change the name of an environment variable with a different variable?

Question

Is there a method to name an environment variable dynamically using another environment variable in a batch file?

Something like

numplayers=3
char%numpla         


        

Answer 1

Given that you are unlikely to know beforehand the number assigned to %numplayers%, here are a few ways you can see the value of the variable:

Set "numplayers=3"
Set "char%numplayers%atk=12"
Call Echo %%char%numplayers%atk%%

 

Set "numplayers=3"
Set "char%numplayers%atk=12"
Set char%numplayers%atk

 

SetLocal EnableDelayedExpansion
Set "numplayers=3"
Set "char%numplayers%atk=12"
Echo !char%numplayers%atk!
