{   The purpose of this request is to establish access to a service access
{ point.  Requests to open connections may be sent and received over the
{ opened service access point.
{   If a reserved service access point is to be opened, then the particular
{ service access point is specified.  Otherwise, a service access point
{ is arbitrarily selected from a pool of allocatable service access points.

{
{ 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.
{
{ RESERVED_SAP: (input) This parameter specifies whether the service access
{       point to be opened is a reserved service access point or an
{       allocatable service access point.  If a reserved service access point
{       is to be opened, then the SAP parameter specifies the service access
{       point to be opened.  Otherwise the input value of that parameter has
{       no meaning.
{
{ SAP: (input, output) This parameter specifies the service access point which
{       is opened as a result of this request.
{
{ ADDRESS: (output) This parameter specifies the network, system, and internet
{       identifiers associated with the service access point.
{
{ STATUS: (output) This parameter specifies the request status.
