You can use xsibatch to execute a script:

	xsibatch -processing -script %TEMP%\test.js 

The -processing flag tells xsibatch to run without a license (you can do this for anything that does not involve rendering).
The -script flag specifies the full path the script file.

If the script file contains functions, you can specify the name of the function to execute with the -main flag. For example, if the .js file contained a function named “test”:

	xsibatch -processing -script %TEMP%\test1.js -main test 

If the main function takes arguments, you can specify them with the -args flag. For example, if the function is defined like this (in JScript)

	function test( sPath, sList, nValue )
	{
		// [body]
	}

then you would specify the arguments like this on the xsibatch command line:

	-args -sPath "%TEMP%" -sList "X,Y,Z" -nValue 22

Putting it all together, the xsibatch command line would look like this:

	xsibatch -processing -script %TEMP%\test1.js -main test -args -sPath "%TEMP%" -sList "X,Y,Z" -nValue 22

Argument values are passed in as strings, and any quotation marks are stripped off.

Here’s a simple example of a test.js:

function test( sPath, sList, nValue )
{
	LogMessage( sPath );
	LogMessage( sList );
	LogMessage( nValue );
	LogMessage( typeof(nValue) );
}

The xsibatch command:

xsibatch -processing -script %TEMP%\test1.js -main test -args -sPath "%TEMP%" -sList "X,Y,Z" -nValue 22
