#### TTABK Prolog

     Name       : HCPTTABK
     Description: Table of Trace Entry Codes
     DSECT      : TTABK
     Function   :
                  This control block maps the structure of the
                  table of trace entry codes as they exist either
                  in HCPTTATB data area, or in free storage created
                  by the SET CPTRACE command processor.
     Located by :
                  PFXTTATB points to the non-explicit (default)
                  copy of the TTABK
                  VMDTTABK in every VMDBK
     Created by :
                  HCPCFASC - SET CPTRACE command processor
                  The HCPTTATB data area, also mapped by this block,
                  is part of the CP resident nucleus
     Deleted by :
                  HCPCFAFR - Fret TTABK's which SET CPTRACE acquired
                  HCPCFALG - Fret (if necessary) a VMDBK's TTABK
                  during LOGOFF processing
                  The HCPTTATB data area is never deleted
     Serialized :
                  TTALOCK - prevents concurrent changes via multiple
                  SET CPTRACE commands
                  MP Defer - TTABK's in free storage are only fretted
                  via the MP defer mechanism (HCPMPDFR).
     Notes      :
            The trace entry codes below are ordered according
            to their frequency of occurrence in the system
            trace tables. As CP tracing evolves and changes,
            so should the order, in order to provide the best
            possible cache utilization.
            The number of fullwords reserved for TTACODES and
            TTACODEN must be equal or greater than the number
            of codes defined in HCPTTABK. The CKMAINT macro is
            used to ensure this by causing an assembly error
            when too many codes are added and there is no room.
            The size of HCPTTABK must not go over 1 page
            since a base register is used to address it.
     General Information -
            Trace Codes x'C0xx' are reserved for VICOM.
            Codes that are added in here, must also be added to
            HCPTTA ASSEMBLE, at entry HCPTTATR.  The only
            exception would be if the trace code you add will
            NOT be controlled by the SET CPTRACE command (which
            should not be the norm).  Note that the way you
            specify the trace entry in HCPTTA must be reflected
            in the CP Command and Utility Reference, under the
            SET CPTRACE command.  That is, with SET CPTRACE, a
            system programmer can activate or deactivate the
            trace function for a specific code, a category of
            codes, or for all codes.  Let's look at an example
            from HCPTTA ASSEMBLE:
              TCTGEN 1,ALLCODES,MINLEN=3
              TCTGEN   2,EXT
              TCTGEN     3,0100        External interruption
              TCTGEN     3,PCDIAG
              TCTGEN       4,3C00      Proc controller diagnose
              TCTGEN       4,3C55      Proc controller diagnose
              TCTGEN     3,PCSERVC
            A system programmer could issue:
      SET CPTRACE OFF ALLCODES    * All tracing is off
      SET CPTRACE OFF EXT         * Turn off 0100, plus category
                                    PCDIAG & PCSERVC, which
                                    include 3C00 & 3C55, etc.
      SET CPTRACE OFF PCDIAG      * Turn off PCDIAG
      SET CPTRACE OFF 3C00        * Turn off 3C00 only
     Deleting a Trace Entry Code
       Starting in V5.4.0, deleted trace entry codes can be
       reused.  Trace entry codes are not permanently assigned.

                 TRACE CODES FOR SPIN LOCK ACQUISITION/RELEASE
                 These trace entries are only cut for formal
                 spin locks if the HCPSYNC and HCPUSYNC macros
                 invoked to obtain or release them have TRACE=YES
                 or TRACE=DEBUGUT specified. If TRACE=DEBUGUT,
                 these trace entries are only cut in the debug
                 unit test (&HCPDBGUT) builds.  Once the code
                 is shipped these traces are not cut because of
                 the adverse performance impact they might create.
