{
{   The purpose of this request is to delete the data for a cycle while
{   preserving the file cycle entry.
{
{   Only a user with control access permission may delete a file cycle data.
{
{   If the file cycle is in use at the time the delete_cycle_data is requested,
{ the data will not be deleted.

{
{ PATH: (input) This parameter specifies the identification of the permanent
{       file.  The path parameter consists of an array of names which identify
{       the path leading through a catalog hierarchy to the desired file.  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 specifies the permanent file
{       whose data is to be deleted. Null names are allowed only for the family
{       name and master catalog name.  If the family name is osc$null_name,
{       the family name of the job making the request will be used.  If the
{       master catalog name is osc$null_name, the user name of the job making
{       the request will be used.
{
{ CYCLE_SELECTOR: (input) This parameter selects the permanent file cycle whose
{       data is to be deleted.
{
{ PASSWORD: (input) This parameter specifies a password that must match the
{       password registered with the file.  If a blank password is specified,
{       it will only match if no password was registered with the file.
{
{ PURGE_CYCLE_OPTIONS: (input) This parameter specifies whether the cycle entry
{       is to be preserved or not, and if to be preserved, also specifies other
{       attributes like label, archive entries and modification date time that
{       are to be preserved.
{
{ STATUS: (output) This parameter returns the request status.
