   8 C ABSTRACT: THIS FUNCTION LOOKS FOR A SPECIFIED NODE WITHIN THE PORTION
   9 C   OF THE CURRENT SUBSET BUFFER BOUNDED BY THE INDICES INV1 AND INV2.
  10 C   IT IS SIMILAR TO BUFR ARCHIVE LIBRARY FUNCTION INVTAG, EXCEPT THAT
  11 C   INVTAG SEARCHES BASED ON THE MNEMONIC CORRESPONDING TO THE NODE.
