Passing Array as an argument in batch script

I have created an array in batch script as:

set arr[1]=a
set arr[2]=b
set arr[3]=c

Now I want to pass this array as an argument to another batch file as follows:

call :processArr.bat arr

I need to do this because in actual the value of %%i in arr[%%i] is variable and it can be greater than 9 and with batch file only 9 arguments can be passed

Moreover its ultra essential that the entire array is passed to the batch file processArr.bat at once

Please help

There's no need to pass the variables as script arguments. When you call processArr.bat, processArr.bat will inherit all the variables defined by the calling script. Here's a demonstration:

test.bat:

@echo off & setlocal

for /L %%I in (0,1,5) do set /a "arr[%%I] = %%I << 2"

call test2.bat

test2.bat:

@echo off & setlocal

echo Checking inheritance...
set arr

Output:

Checking inheritance...
arr[0]=0
arr[1]=4
arr[2]=8
arr[3]=12
arr[4]=16
arr[5]=20
