| GENERAL DESCRIPTION |
The Unwinder was originally written as part of OE/RR in
the namespace OR. When the Unwinder functionality was separated into the XQOR
routines, all the links to OE/RR were isolated into the routine, XQORO. This
routine uses OE/RR variables, and calls into OE/RR entry points. The
following integration agreements are needed to support this routine (XQORO).
OE/RR Variables: The XQORO routine makes sure OE/RR variables are set to the
proper values between each protocol that is executed. The following variables
are killed between each protocol to protect the OE/RR environment -
ORIFN,ORCOST,ORIT,ORSTRT,ORSTOP,ORTO,ORPURG,ORTX,ORSTS,ORPK,ORLOG,
ORPCL,OR,ORZ,ORNS
The following variables are reset between each protocol -
ORVP,ORPV,ORL,ORTS,ORDUZ,ORNP,OROLOC,ORGY,ORACTION,OROLD,ORNS,
ORTX,ORUP
ORPRFRM is used in conjunction with response time monitoring.
