Is CMM-Manager's VBScript a custom syntax?

Is CMM-Manager's VBScript a custom syntax?

Hello,
Just wondering- does anyone know if the VBScript in CMM Manager uses custom syntax that differs from standard Visual Basic? And is it simplified to only focus on the possible needs, application and scenarios used for a CMM? Not much of a programmer myself outside knowing what basic things like Arrays do, If statements, For loops and Do-Whiles. nor do I know Visual Basic in its default form. If its simplified to only focus on CMM related needs I think that's great, as it only helps me from going off the rails in trying to do stuff with it.

 I got a little confused when online general Visual Basic tutorials and guides seem different, and I am guessing to only focus on and use just CMM Manager provided tutorials and documentation for scripting?

Thanks!
