Toplevel vs Open vs start using

[Todd Geist]

Hello,

I have used 3 different methods to "Open" a stack.

Open
  Just to open a stack and draw a window.

start using
    for opening a library file to get at it's functions and scripts.

Toplevel
    First I load a stack into a variable and then use toplevel and hide it.
I use this to open stacks that I use to store data in custom properties.

I am not clear on the distinctions here.  They all show up in the
application browser ( or Constellations Object Gadget).  I have lots of
questions but these will have to do.

Is a stack opened by "start using" just loaded into Memory but not opened?

Should I always call "Stop using" right after I am done with start using?

Does "toplevel" do the same thing as "Open"

Can I open stack invisibly?


Thanks  again

Todd
