{
{   This request causes the connection attributes associated with an
{ instance-of-open to be effected immediately.
{
{   This request provides a means to prevent the latent effecting of connection
{ attributes, specifically, the transparent_mode related attributes:
{
{                  input_editing_mode
{                  transparent_character_mode
{                  transparent_length_mode
{                  transparent_timeout_mode
{                  transparent_message_length
{                  transparent_forward_character
{                  transparent_terminate_character
{
{   As an example, if a program leaves the terminal in transparent mode after
{ receiving input in transparent mode and desires immediately to continue
{ execution in non-transparent mode, it can do so by calling this request and
{ passing it the file_identifier of an instance-of-open whose
{ input_editing_mode is ifc$normal_edit.  Otherwise the terminal remains in
{ transparent mode until an input request is executed for a file_identifier
{ whose input_editing_mode is ifc$normal_edit.  This immediate effecting of
{ non-transparent mode may be desired to allow user interrupts.
{
{   As an example, if a program desires the terminal to be in transparent mode
{ immediately before continuing execution, it can do so by calling this request
{ and passing it the file_identifier of an instance-of-open whose
{ input_editing_mode is ifc$trans_edit.  Otherwise the terminal remains in
{ non-transparent mode until an input request is executed for a file_identifier
{ whose input_editing_mode is ifc$trans_edit.  This immediate effecting of
{ transparent mode may be desired for a program which expects typed-ahead input
{ and wants the input to be delivered in transparent mode.
{
{   This request achieves the same results as AMP$FLUSH for a terminal file
{ except that AMP$FLUSH will not immediately effect the transparent_mode
{ related attributes.
{
{       IFP$IMMEDIATE_ATTRIBUTE_FLUSH (FILE_IDENTIFIER, STATUS)
{
{ FILE_IDENTIFIER: (input) File identifier established for this
{       instance-of-open for which connection attributes are to be effected.
{
{ STATUS: (output) This parameter is used to return the request status.
{       CONDITIONS:
