Batch Script - Functions with Parameters
Advertisements
Functions can work with parameters by simply passing them when a call is made to the function.
Syntax
Call :function_name parameter1, parameter2… parametern
The parameters can then be accessed from within the function by using the tilde (~) character along with the positional number of the parameter.
Following example shows how a function can be called with parameters.
Example
@echo off SETLOCAL CALL :Display 5 , 10 EXIT /B %ERRORLEVEL% :Display echo The value of parameter 1 is %~1 echo The value of parameter 2 is %~2 EXIT /B 0
As seen in the above example, ~1 is used to access the first parameter sent to the function, similarly ~2 is used to access the second parameter.
Output
The above command produces the following output.
The value of parameter 1 is 5 The value of parameter 2 is 10
