{
{   The purpose of  this request is to establish a new active set table entry.
{ This includes finding  an  unused  entry  and  initializing  all  fields  as
{ indicated.  This request may be used on a create set or when a master volume
{ becomes active.  This routine initializes the  p_member_entry_list  to  NIL,
{ the  master_ever_up  field  to  TRUE, the number_of_jobs_using_set to 0, the
{ pf_root_ever_stored to FALSE, and the pf_lock is  initialized  to  unlocked.
{ All other fields are initialized to the values input to this procedure.

{
{ SET_NAME:  (input)  This parameter specifies the set name for the new active
{       set table entry.
{
{ UNIQUE_SET: (input) This parameter specifies the unique set name.
{
{ MASTER_VOL: (input) This parameter specifies the name of the  master  volume
{       of the set.
{
{ MASTER_INTERNAL_VSN:  (input) This parameter specifies the internal vsn name
{       of the master volume of the set.
{
{ ACTIVE_VOLUME_TABLE_INDEX:  (input)  This  parameter  specifies  the  active
{       volume table index for the master volume.  This index is obtained from
{       device management.  The  master  volume  is  assumed  active  on  this
{       request, and this parameter must be specified correctly.
{
{ SET_OWNER:  (input) This parameter specifies the identification of the owner
{       of the set.
{
{ ACCESS_STATUS: (input) This parameter specifies whether to  allow  permanent
{       file access to the set.
{
{ DM_PACKET_STORAGE:  (input)  This  parameter specifies the device management
{       packet storage for the master volume.
{
{ AST_INDEX: (output) This parameter returns the index of  the  newly  created
{       active set table entry.
{
{ STATUS: (output) This parameter returns the request status.
