Library /sys$common/syshlp/dbg$help.hlb DEBUG, DEACTIVATE, BREAK, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    User-defined breakpoints are activated when you set them with
    the SET BREAK command. Predefined breakpoints are activated by
    default. Use the DEACTIVATE BREAK command to deactivate one or
    more breakpoints.

    If you deactivate a breakpoint, the debugger ignores the
    breakpoint during program execution. To activate a deactivated
    breakpoint, use the ACTIVATE BREAK command. You can activate and
    deactivate user-defined and predefined breakpoints separately.
    Activating and deactivating breakpoints enables you to run and
    rerun your program with or without breakpoints without having to
    cancel and then reset them. By default, the RERUN command saves
    the current state of all breakpoints (activated or deactivated).

    To check if a breakpoint is deactivated, use the SHOW BREAK
    command.
