{
{   The purpose of this request is to obtain the contents of a PP's A, K, P,
{ and Q registers.  The PP must previously been reserved to the requesting
{ job.  The accuracy of the result of this request is IOU design dependent
{ unless the PP is in a one instruction loop or is hung on a data transfer
{ between itself and Central Memory or a data channel.  Because of hardware
{ limitations described above, the use of this interface is limited to aiding
{ the determination if a PP is hung.  One would have to sample the PP's P
{ register several times to see if the value is changing; however, this is not
{ conclusive.  Refer to the CMP$IDLE_PP request if more precision is required.

{       CMP$GET_PP_REGISTERS (PP_IDENTIFICATION, REGISTERS, STATUS)
{
{ PP_IDENTIFICATION: (input)  This parameter specifies the identity of the PP
{       whose registers are desired.
{
{ REGISTERS: (output)  This parameter specifies the content of the PP's
{       registers.  The value of each register is stored right-justified with
{       zero fill in the corresponding component of this parameter.  If the PP
{       is in a hardware-idled state, the K register will contain the value
{       107700(8).
{
{ STATUS: (output) This parameter specifies the request status.
