---

This is used to extract characters from the beginning of a string.

Example

@echo off 
set str = Helloworld 
echo %str% 

set str = %str:~0,5% 
echo %str%

The key thing to note about the above program is, ~0,5 is used to specify the characters which needs to be displayed. In this case, we are saying character 0 to 5 should be displayed.

Output

The above command produces the following output.

Helloworld 
Hello
