{

   L_INT             nRet; 
   /* find the group with that name */ 
   nRet = L_VecGetGroupByName( pVector, pszOldName, &Group ); 
   if( nRet != SUCCESS )

   /* get this group for editing */ 
   nRet = L_VecGetGroup( pVector, &Group, &GroupDesc );

      return nRet; 
   /* set new name */ 
   lstrcpy( GroupDesc.szName, pszNewName ); 
   /* set back and clean up */ 
   nRet = L_VecSetGroup( pVector, &Group, &GroupDesc ); 
   if(nRet != SUCCESS) 
      return nRet;
