This function may be used to specify the program and command line arguments which functions like Open will use for opening command files.

CopyUsing Emacs to open command files

onLoad() := CommandFile.SetCommandLineForOpen(emacsclientw.exe, -n);

The program emacsclientw.exe may be used externally to open files in a running instance of the editor Emacs. The command line argument -n specifies that the calling process should exit once the file has been opened rather than waiting for a signal that editing is complete.

Here SetCommandLineForOpen is called not by a voice command but by defining an onLoad function. Putting this code in _global.vcl will cause emacsclientw.exe -n to be used for opening command files without further action on your part.
