1.DBG> SHOW BREAK
      breakpoint at SUB1\LOOP
      breakpoint at MAIN\MAIN+1F
         do (EX SUB1\D ; EX/SYMBOLIC PSL; GO)
      breakpoint at routine SUB2\SUB2
         /after: 2
      DBG>

      The SHOW BREAK command identifies all breakpoints that are
      currently set. This example indicates user-defined breakpoints
      that are triggered whenever execution reaches SUB1\LOOP,
      MAIN\MAIN, and SUB2\SUB2, respectively.

    2.DBG> SHOW BREAK/PREDEFINED
      predefined breakpoint on Ada event "DEPENDENTS_EXCEPTION"
         for any value
      predefined breakpoint on Ada event "EXCEPTION_TERMINATED"
         for any value
      DBG>

      This command identifies the predefined breakpoints that are
      currently set. The example shows two predefined breakpoints,
      which are associated with Ada tasking exception events. These
      breakpoints are set automatically by the debugger for all Ada
      programs and for any mixed language program that is linked with
      an Ada module.
