Library /sys$common/syshlp/dbg$uihelp.hlb DEBUGUI, cnt_button_hlp  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The push-button view on the main window contains push buttons that
  correspond to debugger commands.  You can modify, add, remove, and
  resequence push buttons and the commands associated with them.

  Use the default push buttons to complete the following functions.

   Push
   Button       Function
   ------       --------
   Stop         Interrupts program execution or a debugger
                operation without ending the debugging
                session.

   Go           Starts or resumes execution from the current
                program location.

   STEP         Executes the program one step unit of
                execution. By default, this is one executable
                line of source code.

   S/in         When execution is suspended at a routine call
                statement, moves execution into the called
                routine just past the start of the routine.
                If not at a routine call statement, this push
                button has the same behavior as the Step push
                button.

   S/ret        Executes the program directly to the end of
                the routine.

   S/call       Executes the program to the next call or
                return instruction.

   EX           Displays, in the command view, the current
                value of a variable whose name you have
                selected in a window.

   E/az         Displays, in the command view, the current
                value of a variable whose name you have
                selected in a window.  The variable is interpreted
                as a zero-terminated ASCII string.

   E/ac         Displays, in the command view, the current
                value of a variable whose name you have
                selected in a window.  The variable is interpreted
                as a counted ASCII string preceded by a one-byte
                count field that contains the length of the string.

   EVAL         Displays, in the command view, the value
                of a language expression in the current language
                (by default, the language of the module containing
                the main program.

   MON          Displays, in the monitor view, a variable name
                that you have selected in a window and the
                current value of that variable. Whenever the
                debugger regains control from your program, it
                automatically checks the value and updates the
                displayed value accordingly.
