Outputs  an  image  of  a form as it would appear when displayed. The
  argument  specifies  the  type  of  output device.  The  legal values
  are  NOESCAPE_SEQUENCE,  ESCAPE_SEQUENCE,  VT100_ESCAPE_SEQUENCE  and
  LN03_ESCAPE_SEQUENCE. NOESCAPE_SEQUENCE, the default, produces output
  for  ordinary  printers.  ESCAPE_SEQUENCE produces output for devices
  that  support  VT100  ANSI  Escape Sequences.   VT100_ESCAPE_SEQUENCE
  produces output for devices that support VT100 ANSI Escape Sequences.
  LN03_ESCAPE_SEQUENCE produces output for  devices  that support  LN03
  Escape Sequences. The default input file type is FRM, and the default
  output file type is LIS.

  FMS/DESCRIPTION/DISPLAY_IMAGE replaces FMS/DESCRIPTION/IMAGE.

  Example:  FMS/DESCRIPTION/DISPLAY_IMAGE=ESCAPE_SEQUENCE FORMLIB1-
                                                            /FORM=FORM1

      The output image file will contain escape sequences so that when
      the  form  is displayed on a VT100 or VT100 compatible terminal,
      the video attributes can be seen as defined.

1  –  Qualifiers

1.1    /FORM_NAME

  library_spec/FORM_NAME=(form_name,...)

  Output  descriptions  for  the  forms specified after the  /FORM_NAME
  qualifier.  The qualifier applies  only to the  immediately preceding
  form library.   If the /FORM_NAME  qualifier  is omitted,  the entire
  library is output.

  To name more than one form, enclose the list in parentheses.

1.2    /LOG

  /LOG
  /NOLOG (D)

  The  /LOG qualifier causes a log of all forms for which  descriptions
  are generated  to  be  output  to the device  SYS$OUTPUT.  The /NOLOG
  form which is the default disables logging.

1.3    /OUTPUT

  /OUTPUT=file_spec (D)
  /NOOUTPUT

  The  /OUTPUT  qualifier  allows  you to supply a name for the  output
  description file.   If  the file specification is omitted  the output
  file name defaults to the same  as the input file with  the type LIS.
  The /NOOUTPUT qualifier causes output to be discarded.
