Debugging
*********

 -- Loadable Function: rline = dbstop (func, line)
     Set a breakpoint in a function

     func
          String representing the function name.  When already in debug mode this should be left out and only the line should be given.

     line
          Line you would like the breakpoint to be set on

     The rline returned is the real line that the breakpoint was set at.

dbclear, dbstatus, dbnext

 -- Loadable Function: dbclear (func, line)
     Delete a breakpoint in a function

     func
          String representing the function name.  When already in debug mode this should be left out and only the line should be given.

     line
          Line where you would like to remove the the breakpoint

     No checking is done to make sure that the line you requested is really a breakpoint.   If you get the wrong line nothing will happen.

dbstop, dbstatus, dbwhere

 -- Loadable Function: lst = dbstatus ([func])
     Return a vector containing the lines on which a function has breakpoints set.

     func
          String representing the function name.  When already in debug mode this should be left out.

dbclear, dbwhere

 -- Loadable Function: dbwhere ()
     Show where we are in the code

dbclear, dbstatus, dbstop

 -- Loadable Function: dbtype ()
     List script file with line numbers.

dbclear, dbstatus, dbstop

 -- Built-in Variable: debug_on_interrupt
     If debug_on_interrupt is nonzero, Octave will try to enter debugging mode when it receives an interrupt signal (typically generated with C-c).  If a second interrupt signal is received before reaching the debugging mode, a normal interrupt will occur. The default value is 0.

 -- Built-in Variable: debug_on_warning
     If the value of debug_on_warning is nonzero, Octave will try to enter the debugger when a warning is encountered.  The default value is 0.

 -- Built-in Variable: debug_on_error
     If the value of debug_on_error is nonzero, Octave will try to enter the debugger when an error is encountered.  This will also inhibit printing of the normal traceback message (you will only see the top-level error message).  The default value is 0.
