variables in namespace

I understand when you create a vlx application it can its own namespace which its function are only available in it unless you export them, how about variables? when you define regular variables with (setq x bla) is that also catchable only in the namespace?

Yes, that's why there's such things as the vl-bb-set & vl-bb-ref, or vl-doc-set & vl-doc-ref, or vl-propagate. Look into the help on those functions, they each have their place, but the easiest to use is vl-propagate.

I wish there was a thanks button,

thanks a lot

You're welcome!
