      WtChar8 *ArgStr,

      Format of ArgStr:

      targetName is a function of <target-type>
 
      the format of valueOld and valueNew also is a function
      of <target-type>:
 
         <target-type>   format
         -------------   ------
         TABLE           full record according to DBD schema (non-virtual columns only)

         VIEW            full record according to DBD schema (non-virtual columns only)
 
         the presence of valueOld and valueNew is a function of
         <trigger-type> and <trigger-type-modifier>
 
            <trigger-type>  <trigger-type-modifier>  valueOld   valueNew
            --------------  -----------------------  --------   --------
