{
{    The purpose of this request is to attach the SYSTEM's Store/Forward
{ Network file as declared by the parameter:  ATTACH_FILE.  However, for every
{ call to this procedure a new instance of open will occur for the local file.
{ The Store/Forward Network file contains information for the Queue File
{ Transfer Facility (QTF or NTF) to aid in transferring queue files between
{ connecting systems.  The connecting systems do NOT have to be directly
{ connected by either CDCNET or LCN.  The systems may be connected together
{ through an intermediate system.
