Roy,
That's what I was referring to, there is no layerstate command in Bricscad like Autocad. Bricscad his the "vl" layerstate series of functions as you pointed out unlike Autocad.
Not saying they cannot be manipulated, it is not the same as Autocad at all. I have several functions utilizing the layerstates and I needed to essentially define a function that distinguished between Bcad & Acad so I could use the same function call for either.
