{
{   The purpose of this request is to purge the contents from a catalog.  The
{ name of the catalog is identified by the last name of the path parameter.
{ The residence of the catalog is identified by the remainder of the path
{ parameter.
{
{   This request only allows contents to be purged from a catalog owned by the
{ user making the request.  In addition, this request does not allow a master
{ catalog to be purged.
{
{       PFP$PURGE_CATALOG_CONTENTS (PATH, PURGE_CATALOG, STATUS)
{
{ PATH: (input) This parameter specifies the identification of a (sub)catalog.
{       The path parameter consists of an array of names which identify the
{       path leading through a catalog hierarchy to the desired (sub)catalog.
{       The first two names specify the family name and master catalog name
{       portion of the path.  By convention, the name of a user's master
{       catalog is the same as the user name.  Subsequent names would specify
{       subcatalogs as applicable.  The last name in the path specifies the
{       (sub)catalog that is to be deleted.
{
{ PURGE_CATALOG: (input) This parameter specifies whether or not the
{       (sub)catalog, whose contents are to be purged, should be purged along
{       with its contents.  This request does not allow purging of a master
{       catalog; however, it does allow the purging of a master catalog's
{       contents.
{
{ STATUS: (output) This parameter returns the request status.
