2.5 Compiler Commands
  Compiling is the process of translating a source program to
  an object module. An object module is an intermediate step
  between source code and an executable image. It contains
  information that the linker uses to create an image.

  VAX BASIC has certain defaults that are in effect each time
  you enter the BASIC environment. Unless you explicitly
  override these defaults, they remain in effect until you leave
  the environment. You can see a listing of these defaults by
  entering the SHOW command when in the BASIC environ-
  ment. The following example displays the standard BASIC
  environment defaults:
  EXAMPLE: Click to display example.

  You can override any of these defaults with qualifiers to the
  COMPILE or SET commands, or with the OPTION state-
  ment in your program. Table 2-1 lists and describes all
  the BASIC compiler commands, including qualifiers to both
  the COMPILE and RUN commands. For more informa-
  tion about the OPTION statement, see the DEC BASIC and
  VAX BASIC for OpenVMS Systems Reference Manual .

  The following sections describe these commands. For more
  detailed information, see the DEC BASIC and VAX BASIC
  for OpenVMS Systems Reference Manual .
