        subroutine hdaccess(itno,iostat)
        integer itno,iostat

  This releases an item. It flushes buffers and waits for i/o to complete.
  For small items that are entirely in memory, these are saved until
  the whole tree is closed before they are written out.

  Input:
    itno        The handle of the item to close up.
    iostat      I/O status indicator. 0 indicates success. Other values
                are standard system error numbers.
