 ** "ActionRequest" and "Action" were present in VUE 3.0, and have a
 ** scratch-pad like function within DtActionInvoke() to get actions
 ** started.  They are not good long-term retainers of information.
 ** Action and ActionRequest are in fact freed when DtActionInvoke()
 ** exits.
 **
 ** "_DtActInvRec" and "_DtActChildRec" have been introduced to retain
 ** information for the entire life of the actions.   Some of the
 ** information from ActionRequest and Action will be copied (mirrored)
 ** up to these structures.
