{
{       The purpose of this routine is to change the state of local or remote
{ host physical identifiers or their logical identifiers in the currently
{ active RHFAM configuration to "ON" or "OFF". This process is valid only
{ when the RHFAM system task is active, and the state change is not preserved
{ when the system task is deactivated.

{
{ PHYSICAL_ID_LIST_P: (input) This parameter specifies the pointer to a list
{   host names that are to have their state, or state of their specified
{   logical identifiers changed.
{
{ LOGICAL_ID_LIST_P: (input) This parameter specifies the pointer to a list
{   of logical identifiers defined under the the specified physical hosts
{   that are to have their states changed. If this value is NIL, only the
{   states of the specified hosts are changed.
{
{ ALL_PIDS_SPECIFIED: (input) This parameter specifies a boolean value
{   which, if TRUE, specifies that all the hosts are to have their state,
{   or state of their specified logical identifiers changed.
{
{ STATE: (input) This parameter specifies a boolean value denoting the new
{   state of the specified identifier. If true, the identifier is set to
{   "OFF" (disabled).
{
{ STATUS: (output) This status returns the result of the request. A status
{   of normal indicates that the specified state changes have been done.
