go stack and start using stack - conformation please?

[David Burgun]

Hi All,

As as I understand it, if you do a "go to StackX" but don't do a  
"start using stackX", then you can send it messages but not call  
functions within StackX.

If you do a "start using StackX" but don't do a go to "StackX" then  
you can call functions in the stack but cannot send.

If do "start using" and "go" then you can send messages and you can  
call functions.

Is this correct??

Many Thanks
All the Best
Dave
