/CROSS_REFERENCE

  The  /CROSS_REFERENCE  qualifier  causes  the  compiler  to   generate   a
  cross-reference listing.

  The format of the /CROSS_REFERENCE qualifier is as follows:

     /[NO]CROSS_REFERENCE[=[NO]KEYWORDS]

  The cross-reference listing shows program symbols, their  class,  and  the
  program lines in which they are referenced.  The /CROSS_REFERENCE=KEYWORDS
  qualifier  specifies  that  the  cross-reference  listing   includes   all
  references  to  VSI  BASIC  keywords.   /CROSS_REFERENCE  is  the  same as
  /CROSS_REFERENCE = NOKEYWORDS.

  The  /NOCROSS_REFERENCE   qualifier   suppresses   the   creation   of   a
  cross-reference  listing.   See  the  HP  BASIC  for OpenVMS Alpha and VAX
  Systems User Manual for more information on cross reference listings.

  The default is /NOCROSS_REFERENCE.
