You can customize the debugger's DECwindows Motif interface as follows:

   -  Define the startup configuration of the debugger windows and views

   -  Show or hide line numbers in the source view at debugger startup

   -  Modify, add, or remove push buttons and associated debugger
      commands

   -  Define the key sequence to display the dialog box for conditional
      and action breakpoints

   -  Define the key sequence to make text selection language-sensitive
      in the source view

   -  Define the character font for text displayed in specific windows
      and views

   -  Define or redefine the commands bound to individual keys on your
      computer's keypad.

  You can control the first three of these customizations interactively
  from the DECwindows Motif interface, as explained in the Additional
  Topics.  In each of these three cases, you can save the current
  settings by choosing Save Options from the Options menu on the main or
  optional view window.

  In addition, you can control all customizations by editing the debugger
  resource file (DECW$USER_DEFAULTS:VMSDEBUG.DAT).
