[ic] Control and Components

[Mike Curtis]

Hi all
 
Interchange 4.9.8 on FreeBSD 5.1
 
I am just starting to get to grips with Interchange, starting with the Foundation demo but I am stuck!!
 
I just cannot get my head around [control component none][control] which covers three lines in the template LEFTONLY_TOP but not descibed in the walkthrough from the doc's
 
I have been through the doc's, the best I have seen to describe above is from the Wiki.  Am I correct in thinking that this is an array type function? 
 
Is 'none' a parameter passed to the Tag?
 
 'none' is not described in the doc's including from the Wiki
 
An example using this function would be very helpful folk's
 
TIA
 
Mike
