Run ZPL Macro on Zemax with ZOS-API

Hello,

I have succesfully connected Zemax with Matlab using the standalone application template of the ZOS-API, and I have also opened a ZMX file. Now, I would like to execute the ZPL macro "TestMacro.ZPL" on it. However, I cannot figure out which is the proper command that allows me to do so.

Is there anyone from Zemax which can help me?

TheApplication = InitConnection();
TheSystem = TheApplication.PrimarySystem;
TheSystem.LoadFile('D:\Test.zmx',false);
% And now... how to execute "TestMacro.ZPL"?
