{ PURPOSE:
{
{ IIP$VTP_OPEN_NETWORK opens a network file and returns the file identifier.
{ It is built for simple one-job/one-terminal applications, so it just uses
{ $LOCAL.$TERMINAL as the filename.
{
{ An application can safely perform startup and shutdown I/O thru the normal
{ AMP$GET_xxx and AMP$PUT_xxx interfaces, including related interfaces for
{ attribute management such as IFP$STORE_TERM_CONN_ATTRIBUTES and
{ IFP$CHANGE_TERMINAL_ATTRIBUTES.  However, to achieve correct and efficient
{ results an application should use the I/O procedures IIP$VTP_GET_NEXT
{ and IIP$VTP_PUT_NEXT in combination for all I/O during the application's main
{ loop.  Any attributes that must be changed during main-loop processing can
{ be done thru IIP$VTP_PUT_NEXT.
{
{       IIP$VTP_OPEN_NETWORK (FILE_IDENTIFIER, STATUS)
{
{ FILE_IDENTIFIER: (input) This parameter specifies the file access
{       identifier established when the file was opened.
{
{ STATUS: (output) This parameter specifies the request status.
