3.3 Running a BASIC Program
  After you link your program, use the DCL command RUN
  to execute it. The RUN command has the following format:
  RUN [/[NO]DEBUG] file-spec [/[NO]DEBUG]

  /[NO]DEBUG
  The /[NO]DEBUG qualifier is optional. Specify the /DEBUG
  qualifier to request the debugger if the image is not linked
  with it. You cannot use /DEBUG on images linked with
  the /NOTRACEBACK qualifier. If the image is linked with
  the /DEBUG qualifier, and you do not want the debugger
  to prompt, use the /NODEBUG qualifier. The default ac-
  tion depends on whether the file is linked with the /DEBUG
  qualifier.

  file-spec
  The name of the file you want to execute.

  The following example executes the image SAMPLE.EXE
  without invoking the debugger:
  $ RUN SAMPLE/NODEBUG

  See Chapter 4 for more information about debugging pro-
  grams.

  During program execution, an image can generate a fatal
  error called an exception condition . When an exception
  condition occurs, BASIC displays an error message. Run-
  time errors can also be issued by other facilities, such as the
  OpenVMS operating system. For more information about
  run-time errors, see Appendix B.
