    Displays information about predefined breakpoints.

1.2    /USER

    Displays information about user-defined breakpoints.

2  –  Description

    The SHOW BREAK command displays information about breakpoints
    that are currently set, including any options such as WHEN or DO
    clauses, /AFTER counts, and so on, and whether the breakpoints
    are deactivated.

    By default, SHOW BREAK displays information about both user-
    defined and predefined breakpoints (if any). This is equivalent
    to entering the SHOW BREAK/USER/PREDEFINED command. User-defined
    breakpoints are set with the SET BREAK command. Predefined
    breakpoints are set automatically when you start the debugger,
    and they depend on the type of program you are debugging.

    If you established a breakpoint using SET BREAK/AFTER:n, the SHOW
    BREAK command displays the current value of the decimal integer
    n, that is, the originally specified integer value minus 1 for
    each time the breakpoint location was reached. (The debugger
    decrements n each time the breakpoint location is reached until
    the value of n is 0, at which time the debugger takes break
    action.)

    On Alpha systems, the SHOW BREAK command does not display
    individual instructions when the break is on a particular class
    of instruction (as with SET BREAK/CALL or SET BREAK/RETURN).

3  –  Examples

    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.
