{
{    The purpose of this request is to establish a transport service access
{ point with the specified T-selector value.  Requests to open connections may
{ be sent or received over the opened service access point.  Note, all received
{ open connection requests can be processed only by the 'SERVER JOB'.  All open
{ connection requests received while the server job is not active will be
{ rejected.  A T-selector is a component of a network address.  Multiple
{ instances of an application may share the T-selector value.  There is not a
{ one-to-one correspondence between a service access point and a T-selector
{ value.

{       NAP$GT_OPEN_SHARED_SAP (MAXIMUM_ACTIVE_CONNECTIONS, SAP_PRIORITY,
{             SELECTOR, SERVER_JOB, SAP, STATUS);
{
{ MAXIMUM_ACTIVE_CONNECTIONS: (input)  This parameter specifies the maximum
{       number of connections that can be established on the service access
{       point.  Attempts to establish a connection which would cause this value
{       to be exceeded are rejected.
{
{ SAP_PRIORITY: (input)  This parameter specifies the priority to be associated
{       with the service access point which is opened as a result of this
{       request.
{
{ SELECTOR: (input)  This parameter specifies the T-selector to be associated
{       with the service access point.
{
{ SERVER_JOB: (input)  This parameter specifies whether the service access
{       point to be opened as a result of this request will be the server.  The
{       server SAP is the only SAP that will receive connect indications.
{
{ SAP: (output)  This parameter specifies the service access point which is
{       opened as a result of this request.
{
{ STATUS: (output)  This parameter specifies the request status.
