Robert,

Perhaps I'm dense, but I fail to grasp your logic. A vanilla FB checkbox button
dialog event returns either:

[A]. An  unchecked event value of 0 (indicating an _activeBtn
[B]. A checked event value of 1 (indicating a  _markedBtn)

Off or on, unchecked or checked, 0 or 1, are the only two values of an old-style FB checkbox.

A programmer can, of course, deactivate the button-- or change its state--  by setting it
to _grayBtn. But an inactive checkbox button does not generate a dialog event and it
would take intervention in code to reactivate it as either active or marked so it can
return a usable value.

As far back as I can remember, the demo below represents the traditional
handling of a vanilla FB checkbox button.

I think you are confusing value and state, which would be easy with a vanilla FB
checkbox because in creating something easy to use, the two parameters are kludged
into one. FB's button( id, _FBGetCtlRawValue ) will only return a button's value, not its state.

I realize in the FB help under "button [function]" it says that

   buttonState = button( btnNum [,selector] )

This wording is unfortunate since "buttonState" returns the actual state of the control in
only a very limited context. The function sees most use in returning  min-max-current values,
the control's handle, hierarchy, etc.

On the other hand, an FB Appearance Button separates the state and value parameters
and allows extended settings such as a mixed value checkbox.
