How to use system.callSystem in extendscript?

I'm trying to undertand if/how I can open an external program from After Effects by using extendscript to send a command through the cmd line (system.callSystem), but can't work it out...

For example, to open a version of Premiere Pro from command line I can use the direct path:

cd C:\Program Files\Adobe\Adobe Premiere Pro CC 2019\ && "Adobe Premiere Pro.exe"

 

But when I try that in extendscript via system.callSystem() it doesn't work:

system.callSystem("cmd.exe /c \"cd C:\Program Files\Adobe\Adobe Premiere Pro CC 2019\ && "Adobe Premiere Pro.exe"\"");

 

How do I pass paths and commands to cmd correctly?

example of running python from extendscript: 

var f = File('C:/Users/mr big/Dropbox/code/python/after effects extend script/mostly black/1.py');
f.execute();

That's helpful to know thanks. But if you were going to tell command prompt to open another application for example VLC... would you do it directly from extendscript? Or would you create a py file then execute that?
