Library /sys$common/syshlp/DBG$HELP.HLB  —  DEBUG  SHOW  TRACE  Examples
    1.DBG> SHOW TRACE
      tracepoint at routine CALC\MULT
      tracepoint on calls:
              RET     RSB     BSBB    JSB     BSBW    CALLG   CALLS
      DBG>

      In this VAX example, the SHOW TRACE command identifies all
      tracepoints that are currently set. This example indicates
      user-defined tracepoints that are triggered whenever execution
      reaches routine MULT in module CALC or one of the instructions
      RET, RSB, BSBB, JSB, BSBW, CALLG, or CALLS.

    2.all> SHOW TRACE/PREDEFINED
      predefined tracepoint on program activation
       DO (SET DISP/DYN/REM/SIZE:64/PROC SRC_ AT H1 SOURCE
              (EXAM/SOURCE .%SOURCE_SCOPE\%PC);
          SET DISP/DYN/REM/SIZE:64/PROC INST_ AT H1 INST
              (EXAM/INSTRUCTION .0\%PC))
      predefined tracepoint on program termination
      all>

      This command identifies the predefined tracepoints that are
      currently set. The example shows the predefined tracepoints
      that are set automatically by the debugger for a multiprocess
      program. The tracepoint on program activation triggers whenever
      a new process comes under debugger control. The DO clause
      creates a process-specific source display named SRC_n and a
      process-specific instruction display named INST_n whenever a
      process activation tracepoint is triggered. The tracepoint on
      program termination triggers whenever a process does an image
      exit.
