{    The purpose of this request is to get pointers to the statistic header,
{ counters and descriptive data in a statistic.

{       LGP$PARSE_STATISTIC (log_entry_p, statistic_buffer_p,
{             statistic_header_p, counters_p, descriptive_data_p, status)
{
{ LOG_ENTRY_P: (input, output)  Specifies a pointer to the sequence containing
{       the log entry to be parsed.  If the log entry requires conversion to a
{       new format, this sequence must be the same size as SFT$STATISTIC_BUFFER
{       in order to allow enough room for the converted statistic to be stored
{       in the sequence.
{
{ STATISTIC_HEADER_P: (output)  Variable to receive a pointer to the statistic
{       header.  If an obsolete statistic is being parsed, the statistic header
{       will be converted to the current format for a statistic header.
{
{ COUNTERS_P: (output)  Variable to receive a pointer to the statistic
{       counters.  If there are no counters on the statistic, a NIL pointer
{       will be returned.
{
{ DESCRIPTIVE_DATA_P: (output)  Variable to receive a pointer to the statistic
{       descriptive data.  If there is no descriptive data, a NIL pointer will
{       be returned.
{
{ STATUS: (output) Variable in which the completion status is returned.
