Get or Set Constraints with Viual Lisp / VBA

I write applications in Visual Lisp
Until recent I used often Dynamic Blocks in my applications.
In my applications I can get and set dynamic properties of dynamic blocks with Visual Lisp [ (vla-getdynamicblockproperties obj) etc. ]

Now I switched to Bricscad and thus want to switch from Autocad's dynamic blocks to Bricscad's parametric blocks.
Is it possible to get and set parameters of parametric blocks with Visual Lisp (or VBA) ?
