How to increment a variable windows dos-batch programming?
There are multiple ways we can increment the variable or counter in batch programming.
- use for loop
for loop is used to run with n number of iterations. for with /L option used to iterate with start=1, stop=1 and end=10 values in expression The number started with 1 and incremented by 1 until the counter is reached 20
@echo off for /L %%n in (1,1,20) do echo %%n
1 2 3 . . 20
Another way without for loop
Initializes variable with value 1
Print the value and increment the variable using
Print the counter up to 20 times.
set counter=1 :begin echo %counter% set /a counter=counter+1 if %counter% EQU 20 goto end goto begin :end
