          (* * rht 8/2/84: Added double columns for when called by the browser, i.e. ReverseLinksFlg=T.

	  Reverse links have prefix "←".)




          (* * rht 11/19/84: Changed strings from "pointer" to "link" and from "label" to "type".)




          (* * rht 2/14/85: Added extra arg OldLinkLabels in the Multiple selection case to display previous choices.)




          (* * rht 10/11/85: Took out printing to prompt window. It's a waste of screen space.)




          (* * rht 10/22/85: Added ReturnListOfListFlg so caller can tell difference between aborting from Stylesheet and 

	  choosing NULL set of links.)




          (* * fgh 11/14/85 Updated to handle NoteFile and card objects.)




          (* * pmi 12/5/86: Modified so that clicking outside of Link type menu is equivalent to choosing **CANCEL** from 

	  menu.)
