{   The purpose of this request is to establish values for file attributes}
{ which were left undefined by the task. This request is provided}
{ for the writer of a file access procedure (fap). Using this request 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 request.}
{   This request may be issued repeatedly during the open processing within}
{ the fap. However, multiple requests to intialize the same attribute is not}
{ supported.}
{   The effect of this request is to initialize the preserved attribute}
{ values as well as those associated with this instance of open. Other}
{ instances of open of this file will inherit these attribute values as the}
{ default.}
{   This request is valid only if issued during the open operation of a new}
{ file. It will be rejected at all other times.}
{   If this request is issued for a sequential or byte_addressable file, only}
{ attributes left undefined by the task and which do not affect the}
{ structure of the file may be initialized.}
{ This request cannot be used to define the following attributes for a}
{ sequential or byte-addressable file:}
{       max_block_length
{       max_record_length
{       record_type
{}

{         STATUS)
{
{ FILE_IDENTIFIER: (input) This parameter specifies the file access identifier}
{       which was an actual parameter passed to the fap making this request.}
{}
{ FILE_ATTRIBUTES: (input) This parameter specifies the attribute values to}
{   be added to the file description.}
{
{ STATUS: (output) This parameter specifies the request status.}
