{
{   The purpose of the procedure is to establish values for file attributes
{ which were left undefined by the task.  This procedure is provided to
{ implement an add_to_file request from a file access procedure (fap).
{ Using this procedure the fap is able to provide more pertinent default
{ values than the Basic Access Method has provided.  Attributes explicitly
{ specified by the task cannot be changed by this procedure.
{   This procedure may be called repeatedly during the open processing within
{ the fap.
{   The effect of this procedure is to initialize the preserved attribute
{ values.  This procedure will only succeed if called during the open
{ operation of a new file.
