These macros provide a method of locally allocating registers without interference with previously allocated registers; thus \declarecount allocates a count for local use, in exactly the same way that \newcount allocations one for global use. The sequence

{... \declarecount\foo ... \newcount\bar ...}

is of course a logical error; any \new* command should be issued before the corresponding \declare* command.
