{
{   The purpose of this request is to return a list of all volumes in a

{
{ SET_NAME: (input) This parameter specifies the name of the set that the
{         information is desired for.
{
{ MASTER_VOL: (output) This parameter returns the name of the master volume
{         of the set.  If bad status, this is undefined.
{
{ MEMBER_VOL_LIST: (output) This parameter returns the list of member volumes
{         in the set.  This does NOT include the master volume.
{         IF status.NORMAL THEN
{           IF actual_number_of_members = UPPERBOUND (member_vol_list) THEN
{             All volumes have been gotten.
{           IF actual_number_of_volumes < UPPERBOUND (member_vol_list) THEN
{             Only the actual number of members are stored in the lower portion
{             of the array.  All other array entries (the upper portion) are
{             undefined.
{           IF actual_number_of_volumes > UPPERBOUND (member_vol_list) THEN
{             The member_vol_list is filled with volumes, but is not big
{             to hold all the volumes.
{             There are (actual_number_of_members -
{             UPPERBOUND(member_vol_list))
{             additional members in the set.
{         IF NOT status.NORMAL THEN this parameter is undefined.
{
{ ACTUAL_NUMBER_OF_MEMBERS: (output) This returns the number of members known
{         to be in the set.  If the master volume has never been active between
{         deadstarts, this number could be inaccurate, reflecting only the
{         number of members that the set manager knows about.
{
{ STATUS: (output) This parameter returns the request status.
