how concatenate two variables in batch script?

Question

I want to do something like this in batch script. Please let me know if this is the proper or possible way to do it or any other way?

set var1=A

set var2=B

set         


        

Answer 1

The way is correct, but can be improved a bit with the extended set-syntax.

set "var=xyz"

Sets the var to the content until the last quotation mark, this ensures that no "hidden" spaces are appended.

Your code would look like

set "var1=A"
set "var2=B"
set "AB=hi"
set "newvar=%var1%%var2%"
echo %newvar% is the concat of var1 and var2
echo !%newvar%! is the indirect content of newvar
