Windows – Adding numbers stored in variables in windows batch script

batchscriptingwindows

I have a loop in a batch script and I would like to do some arithmetics with the loop counter. I found out how to evaluate expressions, how to add numbers here: Evaluating expressions in windows batch script

How do I do the same but with variables?

For example:

set x = 100
for /L %%i in (1,1,5) do (
    set Result=0
    set /a Result = %%i+%%x
    echo %Result%
)

As output I would expect

101
102
103
104
105

Thanks!

You really should move away from Batch files.

@echo off

setlocal enabledelayedexpansion

set x=100
set result=0

for /L %%i in (1,1,5) do (

  set /A result=!x! + %%i

  echo !result!
)

endlocal
