    ---Purpose : Simply gives a prompt for a conversational action on standard
    --           input/output. Returns the status of a 

    WhatIges (ent : IGESEntity from IGESData; G : Graph from Interface;
    	      sup : out IGESEntity from IGESData; index : out Integer)
    	returns Integer;
    ---Purpose : Gives a quick analysis of an IGES Entity in the context of a
    --           model (i.e. a File) described by a Graph.
    --           Returned values are :
    --           <sup> : the most meaningfull super entity, if any (else Null)
    --           <index> : meaningfull index relating to super entity, if any
    --           <returned> : a status which helps exploitation of <sup>, by
    --             giving a case
    --             (normally, types of <ent> and <sup> should suffice to
    --             known the case)
